I was struck by this:

> METR’s randomized controlled trial (July 2025; updated February 24, 2026) with 16 experienced open-source developers found that participants using AI were 19% slower, not faster. Developers expected AI to speed them up, and after the measured slowdown had already occurred, they still believed AI had sped them up by 20%. These were not junior developers but experienced open-source maintainers. If even THEY could not tell in this setup, subjective impressions alone are probably not a reliable performance measure.

…and how it matches my own ‘traffic’ behavior/emotions. I’m much happier driving a longer distance - and taking longer - if it means not sitting stopped in traffic, because then I’m always moving and making progress. I know this is unreasonable and inefficient, so I try not to give in to it - to my emotional detriment.
