Looking at the weird and wonderful picture of an unlikely lump of materials with wires hanging off, it’s easy to dismiss. A laboratory experiment that drew together theory and practice to produce a brand-new electrical device. Not something that occurred in nature. Even though its behaviour is of that of materials in nature.
Certainly, the implications of this experiment could not have been fully understood at the time. That said, progress to industrialise this new device was rapid. By the time of 1956, the “inventors” were awarded a Nobel Prize in Physics. In 1947, the transistor, was a fruitful combination of science and practical thinking in a laboratory where that was encouraged.
Bell Laboratories, given its history was a logical place for arguably the most important modern invention to be first put together. Arguing over “most important” there are several matters to consider. For one, how universal, how ubiquitous would this humble device become? Would it have a dramatic impact of everyday life for decades after its invention? Would it change every aspect of human organisation? Would its design, development and production become essential to the world? The simple answer – yes.
My first encounter with the germanium transistor was as a boy in the 1970s. Stripping them out of junked radios and record player amplifiers. Building simple circuits. PNP germanium junction transistors were tiny tin cans with three colour coded leads. With a soldering iron and a primitive breadboard there were plenty of designs in popular magazines to copy. Now, this is considered as vintage technology since germanium has long given way to silicon.
The clock, the radio, the bathroom scales, my shaver, my toothbrush, even in my bathroom every appliance contains circuits that are transistor based. It would be possible to live without some of these items, or at least substitute them with the mechanical versions, but that’s only for eccentrics, museums and heritage houses.
In 1947, the prototype transistor was on a bench being studied. It came along too late to play a part in the huge leap forward technology made during World War II. What became apparent is that the technology that had been developed using thermionic valves was convertible into a transistor-based versions. Size shrank and performance improved dramatically.
What’s my message? It’s another way of looking at so called artificial intelligence. Technology doesn’t come out of the blue. It doesn’t plot new pathways in the first years of its invention. It often takes things we already do and speeds them up or makes them cheaper or makes them more lethal.
We create another stepping stone upon which further developments can take place. So, maybe there is a South Sea Bubble about to burst. Much of the frantic investment that has taken place assumes that artificial intelligence is of itself a wonder. Let’s say it isn’t. The wonder is what it will allow us to do. Much of that side of the coin is a massive unknown. Much as the three who invented the solid-state transistor could not have envisaged tens of millions of them stuffed inside every computer chip on the planet.
Vintage germanium components are sough after by specialists. Apparently, audio amplifiers sound better to those who are sensitive to certain musical tones. Artificial intelligence has a proliferation of applications. A lot are gimmicks. Some are extremely serious.
