So a basically trivial improvement in other words.

How is that trivial? Even one task done a few times a week taking half an hour less is at least a 2% increase in productivity (assuming these tasks are work related and a 40 hour work week). "A lot" of such tasks would easily add up to 10%+.

I believe his statement lies in the fact that wealth is not money, but productivity.

He's saying if every atom of the economy is n% more productive, that will grow the economy by n%.

Half an hour of time recovered using a system not specialized to the work at hand. With better tooling and integrations that could scale to several hours a day spent doing more valuable work.

With the first generation of tools.

If there's a sure-fire early way to make money from AI, it's going to involve betting against people who blow it off.

I don't blow off the future. But I do think there's a lot of excess hype currently.

I save at least 10 hours a week using ChatGPT. Likely more.
