What this article touches on is why I focused only on the serverless part with my project https://saasufy.com/ and why didn't implement any frontend UI for it (besides the control panel which is only concerned with backend concepts like schema definitions, auth, access control...). Now Claude is allowing generation and hosting of UI apps directly from their chat interface so it would be reinventing the wheel to build a UI.

AI companies are going to be working really hard to ensure that users do not bypass their chat interface because AI APIs don't provide much lock-in factor for them.
