> but it also increases the quality of the higher-tier

I truly don't see this happening anymore. Maybe it did before?

If there's real competition, maybe this does happen. We don't have it and it'll never last in capitalism since one or a few companies will always win at some point.

If you're a higher tier X, cheaper processes means you'll just enjoy bigger profit margins and eventually decide to start the enshittification phase since you're a monopoly/oligopoly, so why not?

As for FOSS, well, we'll have more crappy AI generated apps that are full of vulnerabilities and will become unmaintainable. We already have hordes of garbage "contributions" to FOSS generated by these AI systems worsening the lives of maintainers.

Is that really higher quality? I reckon it's only higher quantity with more potential to lower quality of even higher-tier software.
