They just do the basic experiment -> ship workflow over and over again, doing whatever optimizes their product in the short term, and never seem to step back and think about the full long-term impact of their changes. They evidently seem to not even consider immediate regressions or negative blowback from users if it's not within the area of expertise of the guy who ships the change.
That is despite their other teams (especially alignment) having a track record of being fairly well thought-out and intelligent.
To the guys at Anthropic's product teams, every problem is a data science problem that you slap an A/B test onto, and they seem to think that the A/B test is all that's needed, and actual verification and thinking things through is overrated af. That's what leads to countless regressions in Claude Code as well as removing claude code from the pro plan in their product page for a few hours (lol).
