    I suspect a substantial part of this is an avalanche of useless testing.

    If you even review PRs still: when was the last time you didn't just skip over tests? And if you ever looked at tests in an LLM-heavy PR, how many of those tests tested something useful, and not just built-ins and trivial behaviours?

    There's at least some awareness in the industry of how LLMs generate a lot of boilerplate in business logic. It feels like we're much less aware of how much of it is in tests.

      Probably half the generated tests in my app are for markdown files.
