Related it seems AI has been effective at forcing my team to care about documentation including good comments. Before when it was just humans reading these things, it felt like there was less motivation to keep things up to date. Now the idea that AI may be using that documentation as part of a knowledge base or in evaluating processes, seems to motivate people to actually spend time updating the internal docs (with some AI help of course).

It is kind of backwards because it would have been great to do it before. But it was never prioritized. Now good internal documentation is seen as essential because it feeds the models.
