A Nobel Prize laureate and London School of Economics professor who said ChatGPT would result in a four-day workweek says the past 12 months have only further convinced him he’s right. Yahoo Finance reports Christopher Pissarides, a professor who specialises in labour economics and the impact of automation, back in April predicted that generative AI would enable employees to be more productive in their roles and therefore spend less time on them.

A few months on, as attention has turned toward safety regulations and other companies have launched rival generative AI platforms—Pissarides feels even more certain about his prediction. "Now, I do believe that [ChatGPT] will improve the quality of work and probably improve productivity even more," he said in an interview with Fortune (paywall), adding that his thoughts on a possible shorter workweek are "more justified."

Pissarides, who won a Nobel Prize in 2010 along with two other academics for their research on the economic effects of unemployment, believes despite fears that fewer hours at work could result in a loss in pay, that won't necessarily be the case. "Pay will not fall because of improvements in productivity," Pissarides said. "Things will be done faster with ChatGPT, for example, with AI. We'd be able to do in four days what we're doing in five days in many professions." Pissarides also cautioned that it will require other factors including greater tech investment and supportive policies before society reaps AI's benefits in earnest.
