Think of the stupidest product you can think of and you likely only know about it because people buy/bought them en masse. AI is no different from any other product; plenty will pay/adopt for exactly the reasons you said. There is powerful motivations for people to feel “ahead” of others (or more informed, or more “cool”, or more knowledgeable, or more experienced, or whatever their ego requires), even if their situation is exactly the same.

That said, I’m not sure I follow your statement of less resistance to the development of internal tools when the opposite seems to be the case; companies (or more specifically developers) are perhaps too quick to think they can just vibe-code a replacement for any vendor in a weekend these days.
