You can build SaaS now. Why are you still buying it?

A thinking-out-loud video, not a tutorial. AI finally made it possible to build your own systems instead of renting 15 SaaS products that all do the same thing, so why are so many builders still just duct-taping tools together? This is me working through build vs buy in the open: why I built AIOS for exactly my needs, where I still choose to buy, and why an operating layer for your business is finally attainable. I don’t have all the answers here, so tell me where I’m wrong.
