Back in 2010-ish, many developers thought that, in the future, they'd all be running their own systems and servicing their own customers and making a good living like that (there would be enough customers for every dev). They didn't expect that the entire industry would be monopolized by a tiny number of companies, everyone using the exact same product, no alternatives or competition, and that the value of our labor would be artificially suppressed down to $0... This happened long before AI. AI is just the latest assault.
It's impossible for a solo developer to find their own customers nowadays. You could literally offer the same product or a better product for cheaper, but you won't be able to find a single customer because it's too centralized. The trust barriers are massive. Nobody has money to try anything except large corporations and they never try any product based on what it offers; it's all business networking.
It's like; the same conditioning which caused business people to pretend that Linux didn't exist for the first few decades has now spread to all non-VC-funded software.
