A study published on Wednesday reported that a group of 65 artificial intelligence specialists from the UK and Japan estimated that robots would take care of around 39% of household chores by 2033.

“Considering that people currently spend almost similar amounts of time on unpaid work as they do on paid work, the social and economic implications of this future of unpaid work could be significant,” wrote the study’s authors from the University of Oxford and Ochanomizu University in Japan.

According to the experts, grocery shopping is expected to be the most likely chore to become automated, while taking care of children and elderly individuals is considered the least likely to be taken over by robots.

Nonetheless, the researchers emphasized that forecasting the future of automation is not an exact science. They also highlighted that the male Japanese experts were the most pessimistic, whereas the male British experts were the most optimistic, based on their responses.

“Expert opinion even on technological issues and perhaps especially on technological issues remains socially contingent,” the authors wrote. “Expert opinion cannot be simply taken as a source of objective ‘ground truth.’”

OpenAI’s ChatGPT bot has recently contributed to a rise in optimism regarding AI, but companies and AI enthusiasts have been anticipating a robot takeover for decades. As early as 2007, Honda and Toyota were said to be in a competition to develop the first robots that could perform tasks, drive cars, and make independent decisions. However, over 15 years later, it seems that such advanced robots are still some distance away from becoming a reality.
