> Wouldn't the bar for software quality go up

No LLM can help companies that didn't care about software quality in the first place. If they did, they wouldn't have fired QA testers. And now that they've been gone for a decade while revenues have soared, why would they bother using LLMs for QA testing when they could execute on the stakeholder's vision instead!

You'd expect to see the majority of benefit to independent devs who previously _couldn't afford_ QA or a full team, and now can. But since the target audience for this stuff is niche, you're less likely to hear about it unless you're plugged into the subcommunities (see e.g. how LLMs have helped with game preservation, retrogaming).
