WFH helped create the AI revolution. RTO could pose its biggest problem.

A baby boom, cleaner air, and AI. The work-from-home revolution might be over, but its impact is still being felt.

But even if you're in the cubicles every day — God bless — the WFH revolution has still affected you.

Nick Bloom, a Stanford economist who's a leading expert on remote work, spoke to BI's Aki Ito about six ways the WFH era fundamentally changed things for us all.

Other effects were more widespread, such as a reduction in nitrogen dioxide in major cities thanks to the new hybrid world.

Add BI in Google so our reporting is easier to find when you’re searching for what matters.

Now that most of us are in the office at least part of the time, that raises questions about how companies will source more training data.

Granted, people still Slack each other in the office. (I've fired off messages to colleagues sitting a few feet away. Sometimes you've got to see if you can actually make them "lol" IRL.)

That's why executives were pushing us back to the office in the first place. For the organic collaboration and innovation that can only occur when rubbing elbows with colleagues. That RTO push could now pose real problems for AI's development.

And at a time when workers are already on edge about losing their jobs to AI, actively recording their every word to improve models won't do much to ease concerns.

At least we've got some WFH babies joining the workforce in a few decades as reinforcements.
