This is questionable. Did generated code decrease the price of software products?
But also, the main claim of the advantages of code generation is that it will make software development cheaper, and will end up making software cheaper. This is currently not necessarily the case because the quality of the code generation is not really there to make actual (reliable) product development cheaper, but it helps a lot with rapid prototyping. Or as I see it, more things are being prototyped and never finished. What also factors into this is that there are not many incentives for big tech companies to lower their prices, because a lot of what they're offering are tools that we need. This is also not the case with generated music.
I think it's too early to say.
You could argue that if software development is low effort due to "vibe coding" then it doesn't have the same value as it once did. Perhaps there'll be a race to the bottom by new entrants to the market who don't need to pay a whole development team and can massively undercut the incumbents. Or perhaps the race to the bottom will be in quality along with price, but the savvy user will see the value the incumbents provide.
