The pushback is not against the improvements themselves, but rather at the claims of what the improvements solve, and the criticisms of people who fall below some threshold at some specific task, with dubious claims about the effect on their overall performance (without actually measuring the overall performance).

It seems to be a common theme among tech people to unfairly extrapolate small, vaguely related things to judge big things, even to the point of rejecting job candidates or firing employees over one of them and then crowing about it on social media (for example the "don't hire losers" post a few days ago).

If someone doesn't like how I work, then don't watch me work. I get paid for the fruits of my work, not how I get there.
