The thing is it’s been like that forever. Good products made by small- to medium-sized businesses have always attracted buyouts where the new owner basically converts the good reputation of the original into money through cutting corners, laying off critical workers, and other strategies that slowly (or quickly) make the product worse. Eventually the formerly good product gets bad enough there’s space in the market for an entrepreneur to introduce a new good product, and the cycle repeats.
I think what’s different now is, since this has gone on unabated for 70+ years, economic inequality means the people with good ideas for products can’t afford to become entrepreneurs anymore. The market openings are there, but the people that made everything so bad now have all the money. So the cycle is broken not by good products staying good, but by bad products having no replacements.
Vibe coding anything more complicated than the most trivial example toy app creates a mountain of security vulnerabilities. Every company that fires human software developers and actually deploys applications entirely written by AI will have their systems hacked immediately. They will either close up shop, hire more software security experts than the number of developers they fired just to keep up with the garbage AI-generated code, or try to hire all of the software developers back.
