Eutelsat OneWeb is a growing global connected community. That’s what the publicity says. Once upon a time I wrote about OneWeb. I wrote about it in the context of Brexit.

One of the touted benefits of Brexit was autonomy, in other words, British innovation leading the way to benefit Britain above all others. It’s that aggressive assertion of sovereignty that was at the core of Brexit. Remember, it wasn’t so long ago that this was part of Brexiters fantasies? 

In the Brexit turbulence the UK Government walked away from the EU’s Galileo programme. The UK no longer participates in the European Galileo or EGNOS programmes[1].

Then in 2020 the UK changed its original post-Brexit position and scraped building a national alternative to the Galileo satellite system[2]. At that time, Business Secretary Alok Sharma offered around $500 million of UK public money to acquire part of an organisation in trouble, called OneWeb.

OneWeb is a commercial Low Earth Orbit (LEO) satellite constellation now with an element of Government ownership. It’s network of satellites doesn’t have a global positioning capability, like Galileo.

To get its satellite network up and running, an expensive business, OneWeb merged with French company Eutelstat. Today, if we look at the 2020 investment made with public money the financial situation doesn’t look good. That doesn’t mean to say that things will not turn around in future years[3].

The Times newspaper has taken a nationalist view of the circumstance[4]. It’s a point that the intellectual property is not in the hands of the UK Government, but the investment could still turn out to be a useful long-term commercial bet. It’s gambling with public money.

As an aside, I’ve been looking at buying a new dishwasher for the kitchen. It’s made me aware of a capability that I had no idea had been developed. Namely, the connection of dishwashers via the web. I think this is what is called the Internet of Things (IoT). So, imagine that, British dishwashers connected by space as a Brexit potential benefit.

However, if there’s a change in the UK Government’s political direction after the next General Election there’s a strong possibility that the UK will return to the EU’s Galileo programme with some manner of partnership. When we get to 2026, we may look back on the decade behind as a vacuum, much like the vacuum of space. A time when an uncertain direction cost a great deal.

Two upfront

One of the fundamentals that remains a part of civil aviation is having two pilots in the cockpit. It’s an indication of the safety related activities of the crew of a civil aircraft. Today, we have a mixture of human control and management. Pilots still fly hands-on when the need arises. The expectation is that throughout their working lives pilots have the competence to do so, at any stage in a flight.

Progressively, since the establishment of aviation’s international order in the 1940s the required crewing of aircraft has changed. Back in September, I visited the de Havilland Aircraft Museum in Hertfordshire. There I walked through the fuselage of a de Havilland DH106 Comet[1]. This was the first turbojet-powered airliner to go into service and it changed the experience of flying forever and a day.

That passenger aircraft, like aircraft of the time, had four crew stations in the cockpit. Two pilots, a navigator and flight engineer. It was the era when electronics consisted of valves in large radio sets and such long since forgotten devices as magnetic amplifiers. The story from the 1940s of IBM saying, “I think there is a world market for maybe five computers” is often repeated.

For modern airliners the navigator and flight engineer have gone. Their functions have not gone. It’s that having a crew member dedicated to the tasks they performed is no longer required. As the world of vacuum-tube electronics gave way to transistors and then to integrated circuits so computing got more powerful, cheaper, and abundant.

With a few significant failures along the way, commercial flying got safer and safer. The wave of change in a human lifetime has affected every mode of transport. More people travel to more places, more safely than ever could have been imagined 80-years ago. Does that mean the path ahead will take a similar shape? Excitable futurologists may paint a colourful picture based on this history.

Let’s get away from the attractive notion of straight lines on graph paper. That idea that progress is assumed to be linear. Tomorrow will be progressively “better” by an incremental advance. That’s not happening now. What we have is differential advances. Some big and some small. 

The aviation safety curve is almost flat. The air traffic curve, with a big hole made by COVID, is climbing again. The technology curve is rapidly accelerating. The environmental impact curve is troubling. The air passenger experience curve may even be at a turning point.

Touchscreen tablets already help flight preparation and management[2]. Flight plan changes can be uploaded and changed with a button press[3]. The squeezing of massive computing power into small spaces is being taken for granted. What does this leave a crew to do?

Back to the start. Two pilots in the cockpit, with executive responsibilities, remains the model that maintains public confidence in civil aviation. The golden rules still apply. Fly, navigate and communicate in that order. Crews, however much technology surrounds them, still need to act when things do not go as expected. Does this mean two cockpit crew forever? I don’t know.

Batteries

We can talk about chemistry. It’s not a strong subject for me. The simple basics, I remember. As far as handling batteries, or at least knowing what they do, I was quite young on first encounter.  

At the back of the farmhouse where I grew up there were several working rooms that that were part of the building. A room we called “egg house” was indeed used to store eggs. That wasn’t its first purpose. In one corner was a copper vat with a small furnace underneath it. I was told this was for sterilising milking machine parts before chemicals took over that role.

On the opposite side of the wide back door corridor was “boot house.” The name was a giveaway as to one of its uses. Boots propped up against the wall. It had a stone mullioned window that looked out on another working room that was part of a later add on. That’s where a shiny stainless-steel milk bulk tank sat filling up most of the space.

Like a lot of obsolete stuff stashed in a corner and then forgotten, eventually they were thrown out. As far as I know. What I speak of is several large round glass jars. They made of thick greenish glass and were about a couple of feet in diameter. Their original purpose was to store sulfuric acid. The acid was an electrolyte used in heavy batteries that were once the backbone of the electrical system of the farm.

My father moved to Goulds Farm in 1938. As I understand it mains electricity didn’t come to the farm until the 1950s. In one of the stone built buildings around the farmyard, there was a single cylinder stationary engine, generator, and DC electric distribution board on the wall. It was like something out of an early Frankenstein movie. Bare metal switches and a couple of round dials for volts and amps. All covered in dust and cobwebs. I never did see the “submarine” lead-acid batteries[1]. I guess they were parts of this early farm electrical system that had a reasonable scrap value and so got sold on.

There were lead-acid batteries in and out of the house in the winter. Heavy tractor batteries often sat in “egg house” charging overnight. Given their cost every little bit of life was squeezed out of them before they were replaced. Some batteries had a second life powering an electric fence.

Now, here we are in 2023. An electrical revolution is underway. It’s fascinating to note some of the objections to electrification. So, wedded to gas and oil that all sorts of spurious arguments get thrown up. Not that there aren’t hazards with each different technology.

Battery technology has advanced at great pace. Chemistry has provided batteries that have huge potential when compared with they predecessor. The race is on to go much further. I’m confident that we’ve a long way to go before every combination and permutation of materials has been exploited for electrical storage. Manufacturing techniques race ahead too.

Lead and acid presented hazards. Ironically, one of them was hydrogen gas emission. In such systems ventilation is a must so that there’s no danger of explosion. Now, hydrogen is heralded as a fuel of the future. Hazards remain but we do get better at managing each and every one.

My message is that electrical technology has both an upside and a downside. Ultimately the upside is much the bigger.

Half empty tool box

When new technologies come along there’s often a catch-up phase. Then we are either frightening ourselves crazy with a moral panic or switch to a – so what? – mode. The last week’s fury of articles on Artificial Intelligence (AI) probed all sorts of possibilities. What’s the enduring legacy of all that talk? Apart from stimulating our imaginations and coming up with some fascinating speculation, what’s going to happen next?

I’m struck by how conventional the response has been, at least from a governmental and regulatory point of view. A little bit more coordination here, a little bit more research there and maybe a new institution to keep an eye on whatever’s going on. Softly, softly as she goes. And I don’t mean the long-gone black and white British TV series of that name[1]. Although the pedestrian nature of the response would fit the series well.

Researchers and innovators are always several steps ahead of legislators and regulators. In addition, there’s the perception that the merest mention of regulation will slow progress and blunt competitiveness. Time and money spent satisfying regulators is considered a drain. However much some politicians think, the scales don’t always have public interest on one side and economic growth on the other.

Regarding AI more than most other rapidly advancing technical topics, we don’t know what we don’t know. That means more coordination turns into to more talk and more possibly groupthink about what’s happening. Believe you me, I’ve been there in the past with technical subjects. There’s a fearful reluctance to step outside contemporary comfort zones. This is often embedded in the terms of reference of working groups and the remit of regulators.

The result of the above is a persistent gap between what’s regulated in the public interest and what’s going on in the real world. A process of catch-up become permanently embedded.

One view of regulation is that there’s three equally important parts, at least in a temporal sense.

Reactive – investigate and fix problems, after the event. Pro-active – Using intelligence to act now. Prognostic – looking ahead in anticipation. Past, present, and future.

I may get predicable in what I say next. The first on the list is necessary, inevitable, and often a core activity. The second is becoming more commonplace. It’s facilitated by seeking data, preforming analysis and being enabled to act. The third is difficult. Having done the first two, it’s to use the best available expertise and knowledge to make forecasts, identify future risks and put in place measures ahead of time.

So, rather than getting a sense that all the available methods and techniques are going to be thrown at the challenge of AI, I see a vacuum emerging. Weak cooperation forums and the fragmentation inherent when each established regulator goes their own way, is almost a hands-off approach. There’s a tendency to follow events rather than shaping what happens next. Innovation friendly regulation can support emerging digital technologies, but it needs to take their risk seriously.

Learn by testing

Back in the mid-1980s, aircraft system integration was part of my stock-in-trade. Project managing the integration of a safety critical system into a large new helicopter. It was a challenging but rewarding job. Rewarding in that there was a successful new aircraft at the end of the day.

For big and expensive development projects there are a great number of risks. The technical ones focus on functionality, performance, and safety. The commercial ones focus on getting the job done on-time and at a reasonable price. Project managers are in the middle of that sandwich.

Naturally, the expectations of corporate managers in the companies that take on these big challenges is that systems and equipment integration can be done to the book. Quickly and without unexpected outcomes. The practical reality is that people must be well prepared and extremely lucky not to encounter setbacks and resets. It’s not just test failures and anomalies that must be investigated and addressed. Systems integrators are working on shifting sand. The more that is known about overall aircraft flight test performance and customers preferences so technical specifications change.

With cockpit display systems, in the early days, that was often feedback from customer pilots who called for changes to the colour, size or shape of the symbology that was displayed on their screens. What can seem a simple post-flight debriefing remark could then turn into a huge change programme.

That was particularly true of safety critical software-based systems. Equipment suppliers may have advanced their design to a state where much of the expensive design validation and verification was complete. Then a system integrator comes up with a whole set of change that need to be done without additional costs and delivered super-fast. Once a flight test programme gets going it can’t be stopped without serious implications. It’s a highly dynamic situation[1].

I’m writing this blog in reaction to the news coming from Vertical Aerospace. Their VX4 prototype aircraft was involved in an flight test incident that did a lot of damage[2]. There’s no doubt this incident can provide data to feedback into the design, performance, and safety of future versions of their aircraft[3]. Integrating complex hardware and software is hard but the rewards are great.

New Walk

It’s a step to the left and then a step to the right. It’s not quite the “Time Warp” that featured in the 1970s rock musical: The Rocky Horror Show.

It’s a little mini dance that people do every day in the streets of Britain. I found myself doing it over the weekend. It’s that moment when you realise that you have lost a sense of what’s around you. A tiny drift away from where you intended to go. Then a step to correct, and look-up and set-off again towards your destination. A wiggle on the pavement.

Maybe this walk didn’t exist before 2006. Well, that is all but in the most exceptional situations. Hand-held devices are not entirely new. What’s much more frequent now is the compulsion to look at the small screen.

The colours, the constant demand for attention, the tickling of our curiosity, the mobile phone has it all. In fact, its dam silly to continue to call our devices “phones.” The primary purpose of these handy devices has long since passed from being able to make telephone calls from any location.

We call them a “mobile”, but the Germans call them a “handy”. An American will call them a cell phone. Given the way we use these ubiquitous hand-held devices, I think the Germans have got it right. The whole essence of the thing is its utility.

Now, if we are fixated with heads down there’s a lot that can go wrong. This has been the source of numerous aviation accidents. Looking up and checking visual references remains a fundamental part of flying. The basics of “see and avoid” are drummed into every new flyer.

On the pavement us poor humans are evolving in a world of every more connected technology. In our heads we have a perception of the world around us as we walk the urban streets. That’s made up of sights, sounds, and even smells. Our brains gather information and then do some spatial and temporal filtering before making sense of where we are and what we need to do to get where we want to go. The eyes, and image processing in the brain are on the top of the list of our normal priorities.

Heads-down attention is drawn to the small screen and away from our surroundings. Staring at the small screen draws us into the content of an e-mail, or a text message, or a cuddly cat picture running around social media. Luckily our other senses are keeping track of the world around us.

The textbook case is where we start to drift in our three-dimensional environment. Not much. It’s a step to the left and not a step to the right. Suddenly there’s a need to correct. Our ever-active brains pick up on the misstep. That’s where our tiny dance comes in and nobody but us may notice.

I’m talking about something that’s almost trivial. Hardly noticeable. However, there are far too many cases where fatalities have resulted from missteps[1]. There’s some evidence that bumping into people and objects is most likely. Slips and falls follow those incidents.

I’ll bet not much is known about the vast number of micro-events like my tiny mobile phone dance. Now, there’s a topic of study for a student of visual perception.

Getting smaller

We are on an unstoppable rollercoaster.

We don’t use the word miniaturisation much. I wonder why? Everyday we take for granted incredibly powerful handheld computing machines. They are only possible because of miniaturisation.

If digital signal processing was your thing in the 1970s, it would have involved several heavy cabinets of electronics. Lots of chunky circuit boards and a reliable way of removing all the heat they generated. As an example, there’s a nice dusty relict of a Cray computer[1] in the Science Museum in London. Later, I’ll read this again on a popular handheld device that has innumerable functions. Just as powerful.

This week, in 2007 the first iPhone was launched[2]. With a reasonably sized touch screen and a camera, it was launched with lots of hype. Rapidly this device started to change not only the marketplace for phones and cameras but the way we live, work and play.

I wasn’t a first adopter. At the time, I think I was faithful to Nokia. But somewhere in a cupboard, I still have an iPhone 3G, the successor to the first iPhone. 16-years on, it feels like there was never a time when we didn’t have the iPhone, or one of its competitors.

Miniaturisation has squeezed capable and flexible digital computing into small spaces. It’s made it possible to concentrate multiple functions into one device. The sheer convenience of that has crushed the non-professional camera marketplace. Streaming music has superseded traditional media, like tape and disks, almost to the point of their extinction.

The societal implications of this technological transformation are much talked and written about but maybe read by few. It’s fascinating to speculate if we have come to the end of Moore’s law[3]. That’s the empirical relationship that seems to hold for semiconductors. So far, Moore’s prediction has held-up well for the semiconductor industry. As the density of semiconductors doubles about every two years, so nothing ever stands still.

We might shrug our shoulders and carry on as if nothing has changed. Or just not care to look at this phenomenon, thinking its irrelevant to the important political machinations of the day. However, the impact of the steps that have led to more and more dependency on personal devices is something we should be concerned about. There’s little, or no possibility of reversion back to more manual ways of doing business. We have been captured by the convenience of affordable internet connected handhelds.

Decarbonisation is the big policy of the day. Miniaturisation is a two-edged sword in this respect. More people, holding more devices, in the billions, which are regularly superseded by the next upgrade all has a downside. Not only that but networks and massive file server farms backing-up the internet as they hungerly consume ever more energy. Thousands of new satellites mean instant connection on any part of the globe.

We are on an unstoppable rollercoaster. We think we have a choice but we don’t.

Chips

Semiconductor superpower. Where have I heard that before? Let’s go back to the moment when the silicon revolution was a topic of popular conversations. Today, as much as people are speaking of AI. It has been difficult to accept that Moore’s Law is real. Early on, the notion that the number of transistors on a microchip would double every two years seemed far fetched.

I remember the 1980s, and the privatisation drive that effectively gave away the country’s technology crown jewels. UK semiconductor manufacturers of the 1980s such as GEC, Plessey, Ferranti and Inmos waned or sold-up[1]. Policy makers of that time saw globalisation as risk free. Now, that looks like selling off the family silver.

At the time, silicon chips were predicted to kill off a substantial percentage of white colour jobs. Only a few people saw the potential for massive new industries to spring-up and employ large numbers of new workers. It’s true that the jobs created were, on the whole, quite different from the ones they displaced. Admin work in a giant insurance office is miles from that of a being an on-line games developer, tester, or marketer.

My point is that Government intervention in technology hasn’t got a good record. That’s not an argument for a hands-off approach. That too has proven to have negative outcomes. I’m often tempted to go back to the story of videotape and VHS against Betamax[2] The better technology is not always the one that wins in the global marketplace. Boring reality and dull pragmatic considerations can tip the balance.

The record shows Government Ministers get swayed by the whizzy, super advanced, “superpower” labels that get stuck on the latest promotion. Let’s face it, a photo opportunity next to an exciting futuristic image gets the media’s heart beating. Marketing hype is not new. It has a role in druming-up investments in risky ventures.

Unquestionable is the intense level of competition in the global semiconductor marketplace. If the UK is to be taken seriously when billions of dollars are placed on the table by others there really must be a matching offer. One billion over a decade will end up getting spread as thin as oil on water. A strong collaboration with other, who have common interests would help. Let’s not forget that doing the “dull stuff” can be highly profitable too.

The open market, in deals of the past, has seen a concentration of power. This is not good for a medium sized country on the edge of a continent. Inward investment is to be welcomed. At the same time strategic domestic protections should have a place. Investments in domestic technology capabilities secures a future.

AI awakens

Artificial Intelligence (AI)[1] is with us. Give it a question and it will answer you. Do it many times, with access to many information sources and it will improve its answer to you. That seems like a computer that can act like a human. In everyday reality, AI mimics a small number of the tasks that “intelligent” humans can do and do with little effort.

AI has a future. It could be immensely useful to humanity. As with other revolutions, it could take the drudgery out of administrative tasks, simple research, and well characterised human activities. One reaction to this is to joke that – I like the drudgery. Certainly, there’s work that could be classified as better done by machine but there’s pleasure to be had in doing that work.

AI will transform many industries but will it ever wake-up[2].  Will it ever become conscious.

A machine acting human is not the same as it becoming conscious. AI mimicking humans can give the appearance of being self-aware but it’s not. Digging deep inside the mechanism it remains a computational machine that knows nothing of its own existence.

We don’t know what it is that can give rise to consciousness. It’s a mystery how it happens within our own brains. It’s not a simple matter. It’s not magic either but it is a product of millions of years of evolution.

Humans learn from our senses. A vast quantity of experiences over millennia have shaped us. Not by our own choosing but by chance and circumstances. Fortunately, a degree of planetary stability has aided this growth from simple life to the complex creatures we are now.

One proposition is that complexity and conscious are linked. That is that conscious in a machine may arise from billions and billions of connections and experiences. It’s an emergent behaviour that arises at some unknown threshold. As such this proposition leaves us with a major dilemma. What if we inadvertently create conscious AI? What do we do at that moment?

Will it be an accidental event? There are far more questions than answers. No wonder there’s a call for more research[3].

Light touch folly

Light touch regulation. Now, there’s a senseless folly. It’s a green light to bad actors wherever they operate. It’s like building a medieval castle’s walls half as thick as planned to save money in the belief that enemies are too stupid to work it out. Saying that the public good far less important than the speed of developments is unwise to say the least.

The INTERNET arrived in the UK in the late 1980s. Now, it seems strange to recount. Clunky Personal Commuters (PCs) and basic e-mail were the hight of sophistication as we moved from an office of typewriters and Tipp-Ex to the simple word processor[1]. Generations will marvel at the primitive nature of our former working lives. Getting scissors and cutting out paper text and pasting it into a better place in a draft document. Tippexing out errors and scribbling notes in the spaces between sentences. Yet, that’s what we did when first certifying many of the commercial airliners in regular use across the globe (Boeing 777. Airbus A320). Desktop computers took centre stage early in the 1990s, but administrations were amid a transition. Clickable icons hit screens in 1990. Gradually and progressively new ways of working evolved.

Microsoft Windows 95 and the INTERNET were heralded as the dawn of a new age. Not much thought was given to PCs being used for criminal or malicious purposes. No more thought than the use of a typewriter to commit crime. That doesn’t mean such considerations were ignored it just means that they were deemed a lower-level importance.

In 2023, everyday there’s a new warning about scammers. Even fake warnings about scammers coming from scammers with the aim of scamming. Identifying whose real and whose a fake is becoming ever more difficult. Being asked to update subscriptions that were never opened in the first places is a good indicator that there’s some dirty work afoot. Notices that accounts are about to be blocked referring to accounts that don’t exist is another.

In 30-years the INTERNET has taken on the good and bad of the greater world. It hasn’t become a safer place. In fact, it’s become a bit like the Wild West[2].

Our digital space continues to evolve but has nowhere near reached its potential. It’s like those great western plains where waggons headed out looking for rich new lands. In any towns on the way the shop fronts are gleaming and inviting but if you look around the back there’s a desperate attempt to keep bad actors at bay.

Only a fraction of the suspicious, emails, texts, and messages get reported. People unconsciously pile up a digital legacy and rarely clean out the trash that accumulates. A rich messiness of personal information can lie hidden to the eyes but just bellow the digital surface.

When politicians and technocrats talk of “light touch regulation” it’s as if none of this matters. In the race to be first in technology, public protection is given a light touch. This can’t be a good way to go.
