“look at how many specialist hosting providers exist for web apps right if it was just about saving the most money every single person would host on AWS but in reality people have different preferences they want more than a generic platform”

Niche solutions exist because cheap-and-generic does not fit most people

Every layer of infrastructure has both an AWS-style raw platform and a thriving ecosystem of specialist tools (Vercel, Render, Fly, Railway) built on top of it. AWS hasn't "killed" the specialists — it enables them. The same logic applies to OpenAI: there is room for hundreds of specialist tools sitting on top of one base model because users buy fit, not raw access.
