I have no idea what this flood of personal-use software is that you think normal people want to produce. Normal people don't even think about software doing a thing until they see an advertisement about software that does a thing. And then they'd rather pay 10 bucks for it than to invent a shittier version of it themselves for $500.
And I'm not being condescending about normal people. Developers often don't think about the possibility of making software that does a particular thing until they actually see software that does that thing. And they're going to also going to prefer to buy than vibe code unless the program is small and insignificant.
