AI will take the jobs of half the world's population by 2045


As we reach the middle of the 21st Century, half the population of the world will lose their job to a machine.

Yes, this is another 'robots will take our jobs' story, and we saw a few of those last year. This latest comes from Moshe Vardi, professor at Rice University, Houston, who delivered a talk to the American Association for the Advancement of Science's exploring one central question: "If machines are capable of doing almost any work humans can do, what will humans do?"

(He also previously gave this talk back in December at the University of Oxford's Ada Lovelace Symposium).

Vardi reckons that half of workers across the globe will be replaced by machines within the next 30 years, wiping out middle-class jobs and "exacerbating inequality". He noted that robots would take over in many spheres of life, including almost fully automated driving (which he predicts will arrive in the next 25 years) and sex robots.

As the Guardian reports, he also observed that this future is likely to mean humans have much more leisure time – indeed we may only work a handful of hours per week, with intelligent machines being relied upon to pick up all the slack.

Work is essential

However, this might not be the utopia we imagine. Vardi warned: "I do not find this a promising future, as I do not find the prospect of leisure-only life appealing. I believe that work is essential to human wellbeing."

Of course, if you don't have to do a job all week long to keep a roof over your head, life doesn't have to become "leisure-only" – you could undertake voluntary work for example. Perhaps Vardi is worried that many won't see it like that, though…

At any rate, it's clear that over the next few decades there are going to be big leaps in AI and robots, and these will have major repercussions on our society.

Previous research has indicated that as soon as 20 years from now, 35% of UK jobs are at high risk of replacement by automation and robotics – and lower paid jobs of under £30,000 per year (around $43,000, AU$60,000) are five times more likely to be affected than higher salaried roles.
