Uber, Moore’s Law and the limits of the technofix

Uber, Moore’s Law and the limits of the technofix

Uber remains a darling of the tech world. It is regarded as a disruptive upstart that recognized the unused capacity of privately-owned automobiles and their owners. It unleashed that capacity on cities worldwide using cellphone technology to provide discount rides to customers, ones who might otherwise have taken traditional taxis or public transportation.

It’s a truism that startups burn through money like bonfires burn through tinder. But nine years in after becoming a worldwide company, Uber is still burning cash—$1 billion in the most recent quarter and $4.5 billion altogether in 2017.

To understand how Uber continues to enchant the investment and tech worlds despite its miserable financial record requires a little background. The dominant metaphor in the tech world is Moore’s Law. Moore’s Law is named for Gordon Moore, a semiconductor pioneer, who noted the doubling of transistors on an integrated circuit about every two years. This rapid progress led to rapid increases in the capabilities of computers in terms of speed, memory and computational power even while prices were coming down dramatically. That progress is also seen in the capabilities of practically everything containing circuits including cellphones, cameras and other digital devices.

As Wikipedia will tell you, Moore’s Law is not a law of physics; it is simply an observation about an historical trend in the semiconductor industry. But so pervasive has been the effect of Moore’s Law on the digitization of our daily lives—for instance, our cellphones have become powerful, portable miniature networked computers with cameras—that we are inclined to believe that Moore’s Law is a kind of mystical force unleashed by the tech industry on modern society.

The future of renewable energy

The future of renewable energy

I’ve been reflecting on the idea that the current energy system is starting to be swept along by a technological revolution somewhat akin to the “revolution” over the last 30 years in computers and telecommunications that has brought personal computers, mobile phones and the internet. Read some of the literature of techno-optimists and it is very common to suggest that Moore’s Law – the doubling of processing power on computers every year – provides an analogue for the sort of change that will apply in renewable energy systems – if only the politicians and carbon vested interest do not get in the way. In support of this idea people commonly point to the rapidity with which renewable systems like solar and wind have developed so far. The main thing is that the political support should be there…

I 60% agree but have severe reservations with carrying the analogy too far. There are some real differences that make the two “revolutions” largely non-comparable:

(1) The digital revolution has brought us many new products that do things we couldn’t do before – computers, mobile phones, the internet. That makes it attractive to people and companies and has sped adoption. The energy revolution does not bring new final end products – the end products are electricity (and heat and motion) which we already had. What it brings are many new ways of generating electricity (and heating and moving things).

(2) To pay for the energy revolution people must pay once for the new technology that generates the energy source (mostly as electricity) and once for products that are adapted to this new energy source (eg a petrol or diesel car to an electric car) – and perhaps a third time for the back up or storage to cope with intermittency in the renewable power source.
