The Tech in My Life #3: Crystal Radio

The first radio I owned was a cat’s whisker or crystal receiver, housed in a chic red plastic box. The outward appearance suggested space age technology; the inward reality was a primitive but robust design, and represented my first hands-on experience of electronics.

The advantages of this gadget were portability, ease of use (just a single tuning dial), and no need for a battery or external power source.

The downsides were: limited amplification (no built-in speaker, and the audio was via a single ear-piece – no WiFi or bluetooth in those days!); the need to be connected to an external aerial (a long length of copper wire dangling out of my bedroom window); and it only received medium wave radio signals.

But the worlds it opened up were endless. This was the days before BBC Radio One, and the height of pirate radio stations such as Radio Caroline and “wonderful” Radio London. Listening to the sounds of the psychedelic sixties aged 6 or 7 were formative years in the development of my musical tastes. And thanks to certain atmospheric conditions I could sometimes hear European stations, which sounded very exotic to my young ears.

The Tech in My Life #2: Goonhilly

After the previous tech-related blog on Telstar, it makes sense to mention Goonhilly, a UK-based satellite dish that has been playing a key role in communications and space exploration for more than 60 years.

Goonhilly received the first trans-Atlantic TV signals transmitted via Telstar, and broadcast them into British homes, in 1962. I was too young at the time to recall seeing those early signs of global communications; but I do remember getting up early in the morning to watch the live broadcasts of the Mexico Olympic Games in 1968, and the Apollo 11 moon landing the following year.

During a family holiday in Cornwall in the mid-1960s, my parents took us on a visit to Goonhilly Downs, including a tour of the satellite tracking station. Of course, it was not really possible to see what the dish was actually doing, but I came away with a small souvenir of this new age of technology.

I was given a short strip of computer punched tape. I had no idea what the holes on this piece of paper meant, or what information they represented. But it felt significant to have hold of this data artefact, which I kept for several years.

After I left high school, one of my first jobs was as an outdoor clerk for a firm of solicitors. This involved spending many hours in the communications room, where among other things, the telex machine was located. The secretaries who sent out telexes from the firm typed the text using a keyboard, and the message came out as a series of holes punched into similar paper tape. The tape was fed back into the machine to play it at a higher speed than could be humanly typed, to transmit the recorded message. Even though faxes were becoming more popular, the legal profession still used telex, not only for speed and for long distance communications, but where the record of a telex transmission was required as proof of delivery.

Goonhilly itself is an icon of both technology and culture, and retains a special place for people of my generation – growing up, its name was synonymous with space and communications. And it has been the inspiration for a number of musical tributes, including a concert to celebrate the 50th anniversary of the first moon landing.

The Tech in My Life #1 – Telstar!

This week’s blog is the first in a series on key technology that has helped to shape my life. It will be a very personal perspective, and obviously it can’t capture every tech development, interface or environment that I have engaged with. But as I hope to establish, my selections do reveal three recurring themes: information, communication, and music. These threads should become apparent in the coming weeks.

First up is a record, “Telstar”, released by The Tornados in 1962.

I have blogged about this record before, mainly from a musical perspective. But as a tech artefact it also provides other context.

It is probably the first 7″ vinyl record that I can recall hearing – and certainly one of the only pieces of music from my early childhood that remains both familiar and intriguing to this day. Maybe it was also the first record I got to play on the family Dansette myself, so there is a reinforced tactile connection with the record as a “data object” and the gramophone player as a “playback device”. And while the tune itself is relatively simple, the arrangement and recording techniques reveal a lot more depth than a normal pop record. For a start, the choice of electronic keyboards, and the treatment of the electric guitar give it a suitably unworldly atmosphere.

More specifically, and without my realising it at the time, it is probably my earliest experience of musique concrète. I distinctly remember putting my ear as close to the speaker as possible to absorb the opening passage of Joe Meek’s sound effects, tape manipulation and general studio wizardry. What were these strange noises? Why did they fascinate me? Was it really music, or was I hearing something else entirely, like signals from outer space?

Which is exactly the point, as “Telstar” is named after the communications satellite of the same name. Leaving aside Joe Meek’s fascination/obsession with spiritualism and the occult, he was something of an autodidact in the studio – if he needed a particular effect (“what would a satellite signal sound like?”), he would create or improvise from whatever technology was to hand (primitive or otherwise).

In coming weeks, the significance of “Telstar” (the satellite) on my childhood will emerge. But if I was ever invited to appear on “Desert Island Discs”, I’m certain that “Telstar” would be included in my playlist of 8 records.

The cost of AI

A variant on Moore’s law is the observation that the financial capital required to launch a new business decreases exponentially as technology gets cheaper.

Pre-internet, and using a notional geometric scale for the purposes of illustration, you might have needed $5m to found and build a new venture. The World Wide Web probably reduced that to $500k, while cloud computing brought it down to $50k. With the expansion of SaaS and API solutions, that cost might have been $5k to get going. Now, vibe coding and $500 of AI prompts can probably launch a new website, build a back end database, implement an e-commerce solution and deploy agentic AI bots to go and find your first customers.

This is a great outcome if measured by a lower barrier to market entry. It also enables founders to “fail fast, fail cheap”, and incentivises innovation by financially de-risking the process.

But even though the cost of AI tools is extraordinarily cheap in terms of the computing and processing power they deliver, there is a huge cost to our rapid adoption of AI that needs to be accounted for.

First, we are seeing corporate lay-offs among tech firms and parts of the service industry that no longer need as many human bodies and minds to operate at scale. So there is a human, economic and societal cost of increased un(der)employment.

Second, traditional skills and expertise are being hugely reduced in perceived value – why pay a graphic artist to design an image when I can use dall-e for free?

Third, as more and more creative tasks are being outsourced or delegated to AI (“create a short story about an F1 race in the style of Ernest Hemingway”) we risk losing our own innate creativity (that comes with experimentation, curiosity, play and reflection). This in turn devalues the creative process itself (thanks to cheaper, AI-enabled production).

Fourth, AI (and the Large Language Models on which it is trained) has no great respect for intellectual property. It doesn’t recognise boundaries between copyright material, content that is subject to creative commons, content that is in the public domain, and content which is publicly available. Again, if copyright owners and original content creators are not recognised or compensated for their work, why would anyone aspire to creating anything original?

Finally, there is the cost of resources (energy, water, rare earth metals) needed to maintain huge AI processing plants and data centres. (But at least this demand is accelerating the development of renewable energy.)

A few years ago, I posted a blog about the importance of the human factor, in the face of technological progress brought by automation and AI. I still remain cautiously optimistic that AI will bring huge benefits, despite the rampant growth of AI in the three years since I wrote that piece. But we are currently in an awkward and comfortable transition phase. If more jobs are lost to AI, and if human-led output is increasingly devalued, perhaps we will need to revisit the debate about Universal Basic Income and other policies to facilitate this transition.
