Technology brings challenges as well as benefits

Peter Stonham

IT’S AN OBVIOUS TRUTH that we live in a world being constantly reshaped by technology. And no more so than in transport.

In preparing just this edition of LTT we have addressed the issues of autonomous and remotely driven vehicles, aerial drone deliveries, smart cross-modal digital payment systems, harnessing data about the stops, stations and nodes in the public transport system, and introducing hydrogen powered buses.

It all adds up to a continuing revolution in how transport is both supplied and used. And that's without specifically considering the wider issue of the accelerating arrival of Artificial Intelligence (AI) applications to replace the human elements of transport provision that were once a massive creator of jobs – and costs – that both the commercial operators and public sector now target for 'efficiency savings'.

We've come a long way down that path already. Starting with the mechanisation of vehicles, when an engine replaced the horses and their grooms, and then when conductors and guards were dispensed with on buses and trains and the docks were stripped of myriads of manual labourers with the advent of containers. And when transport operators started using computers to schedule, then track and control the movements of their rolling stock.

Listening to the recently completed 2021 BBC Reith Lectures by Professor Stuart Russell, he drove home both the significance of the Artificial Intelligence explosion now taking place, and how many implications and consequences have been far from yet fully considered or grasped.

How will the economy adapt as work is increasingly done by machines?

Russell, Professor of Computer Science and founder of the Center for Human-Compatible Artificial Intelligence at the University of California, Berkeley, explored how we can retain power over machines more powerful than ourselves, and even the risk of an apocalyptic future.

He quoted the words of former Reith lecturer Professor Stephen Hawking in 2014, “Success in creating AI would be the biggest event in human history. Unfortunately, it might also be the last, unless we learn how to avoid the risks.”

In one of his lectures Russell explored one of the most sharply focussed issues of AI – the threat to jobs, and the role of work in human life. How will the economy adapt as work is increasingly done by machines? Economists’ forecasts range from rosy scenarios of human-AI teamwork, to dystopic visions in which most people are excluded from the economy altogether.

There doesn't yet seem to be much discussion in the transport community of how these kinds of issues will affect both the operation of the sector, and its role in the bigger scheme of things. And yet massive changes could be only a few years away.

It often feels like the role of technology is regarded as simply to help us do the same as now, only better. It could surely mean a great deal more than that – both for good, and ill.

Russell concluded his lectures with the call for a new way to think about AI systems and human-AI coexistence based on three principles – chief among them the idea that machines should know that they don’t know what humans’ true objectives are. Machines designed according to the new model should be, Russell suggests, deferential to humans, cautious and minimally invasive in their behaviour. And, crucially, willing to be switched off. Even back in 2001 HAL wasn't so keen on that.

Time for a wider look at transport’s trickiest challenges
THERE’S NO SHORTAGE of opinion and ideas about the best way forward for transport. The problem is that they can’t all be pursued, and not all of the ideas and policies being proposed are rooted in either science or evidence. They represent a lot of ‘conventional wisdom’, and some ‘unconventional wisdom’ both of which have not always been subject to either practical or even laboratory testing for their efficacy and current and future circumstances.
Ideals worth aiming for in 2023
HAPPY NEW YEAR to all our LTT readers. It is not so easy to see a positive and rewarding year ahead, however. And if we looked back to this time 12 months ago, we might have felt more positive then than we do now given our lack of knowledge about impending crises and unforeseen problems ahead, which will undoubtedly be familiar to us all, and only depressing to list again here. Let’s hope there are not too many similar shocks to come this year.
Not quite what we planned for - but still an asset

Growing, Growing - Gone? Time to re-think our future
Do recent figures signal the end of steady upward population growth in the UK, and do they lift the consequent pressures on land use and traffic congestion? And if so, is this an opportunity to take a new look at our values and at the pursuit of endless economic growth, asks Martina Juvara. Might balance be better than growth - and make far more sense for sustainable human development?
The Boiling Point. What’s missing if it isn’t the experience?
ARE PERSONAL EXPERIENCES, and demonstrable signals that something untoward is happening, a better way to change thinking and behaviour than hearing the wisdom of experts and the warnings of doomsayers? Or is it possible to even miss the implications of those too? It’s surely worth asking in the light of last week’s unprecedented extreme temperatures in the UK, and even worse in other countries, and the continuing impacts of fossil-fuel supply shortages and massive price rises.
