And test creation and maintenance. AI-generated tests will often embed existing bugs as testable patterns that fail when fixed or rely on empty asserts to increase coverage. A human author generally knows better. Coverage is increasingly becoming theater and you have runtime testing eating up CI resources and time with bloated, unnecessary, untargeted testslop that haven't been mutation tested or a human eye assessing if the business logic is actually represented.

It's really the smaller firms which are able to learn quick adaptations that will win out in the long-run of this thing. Legacy firms with institutionalized bureaucracies are relying on gobbling up competitors and creating vertical monopolies while pushing out the worst slop - it's why GH goes down, why Meta products are buggy as hell now, and everything feels like it's unpolished MVPs these days.
