What If Semiconductors Didn’t Exist?

There are moments when it’s dark and grey outside. Moments to ponder a what-if. That’s a what-if something hadn’t happened or physical laws aren’t what they have been found to be.

In my youth I do remember making a “crystal” radio receiver[1]. A relatively fragile germanium diode and a couple of other components scraped from junk radios, record players and TV sets. It worked quite well. It was a good introduction to the theory of amplitude modulation (AM). The diode detector demodulates the radio signal and provides a faint signal to listen to. The whole arrangement is crude but cheap and simple. It depends on that useful device – a semiconductor diode.

My what-if is right there in plain sight. Let’s put aside the physical laws that give certain materials their properties. What-if the whole world of semiconductors didn’t exist?

The most immediate repercussion is that this keyboard, screen and computer would look entirely different, if it existed at all. What I’m doing now is dependent upon millions of semiconductors all doing exactly what they’ve been designed to do. Easy to take for granted – isn’t it. Our modern world is enabled by semiconductors.

Electronics would still exist. Before semiconductors were understood thermionic valves provided the ways and means to control electrical signals. Don’t think that valves[2] have disappeared in the 21st century. There’re enthusiasts who prefer them for amplification. The sound is better (different) – so they say.

Unlike semiconductors, thermionic valves don’t lend themselves to miniaturisation. A world without semiconductors would be populated by machines that are considerably larger and heavier than those of today. But it wouldn’t be a world without sophistication. Just look at the English Electric Canberra[3]. An incredibly capable aircraft for its day. It lived a long life. Without a semiconductor in sight.

It’s difficult to imagine e-mail without semiconductors. It’s difficult to imagine the INTERNET or the mobile phone. Not that such key markets wouldn’t be satisfied by some other means. The transition to a global dependency on digital systems would probably have been considerably slowed. Maybe the pace of life wouldn’t have accelerated so much.

I don’t think we would have been trapped in a 1950s like society. Only that patterns of work would have taken a different developmental path. Would it have been the one painted in the grim tale of 1984? No. Even that takes a position of a freezing of the state of human progress.

A non-semiconductor existence would have meant less proliferation of electronic devices. It might have led to a less wasteful society where repairing equipment was given more weight.

I suspect that large global corporations would inevitably have a hold over whatever technology was most popular. That side of human behaviour is technology agnostic.

Beware

There is some corrupt b****** out there in INTERNET land. They would dip their hand in your pockets and take whatever they can in a second. It’s downright evil. The wild-west element of the INTERNET has never gone away. It’s a global problem.

I’ve never had a Netflix account. Maybe that’s unusual. It would be nice to have one but, personally I’m not convinced that the costs are warranted. Not today. I’m slow to step on the streaming bandwagon. I still have a pile of DVDs and CDs. Yes, I’m a primitive. In some things an early adopter but when it comes to services that require regular payments, I’m cautious.

As regular as clockwork junk e-mails turn-up saying that I need to update my payment details, or my Netflix account will be suspended. Followed by an exclamation mark. On closer inspection they are amateurish cons. In fact, it’s good that the junk mail filter can see through them as they come in.

This kind of fishing is criminal. Somewhere there’s a group on con artists thinking up ever more devious ways of taking money from people. The amateurish ones may not be a threat to me, but I wonder how many people they do catch. Even one in a hundred thousand would net a nice return for virtually zero outlay.

It may be the case that lots of people think that they are not so stupid as to fall for these blatant entrapments. What’s concerning is that cybercrime is becoming ever more inventive. We’ve yet to see what developments in intelligent algorithms will do to this landscape.

The best advice around is to never ever, I mean never ever, give personal payment details in response to an unwanted request. Most honest organisations make a point of saying that they will never request bank details in unsolicited e-mails. Unjustified urgency and a threatening tone are another sign that something is wrong.

Electronic means, namely the digital economy is not as robust as the traditional over the counter transaction. Organisations are aware of this fact. Warnings saying that they will not take responsibility if money is transferred to an incorrect bank account are commonplace.

The digital economy has been a boom for the major banks. High Streets up and down the country now have grand imposing buildings that are coffee shops, restaurants and, in the case of my town a kitchen showroom. Banks have retreated from face-to-face relationships. The responsibility for being aware of the potential for cybercrime has been firmly placed on the shoulders of the individual.

Talking to people remains important. Certainly, if a request for payment seems strange or unexpected there’s no substitute for picking up the phone, however tedious that process can be. Notes, and paper records still matter or, at least, they still matter to me.
