I would like to crank this prediction up a bit more. I think we are pretty close that it doesn't make sense to have simple client apps anymore. Why shouldn't the LLM do it all?

Let's say a simple single purpose web app such as Calendly. Why should I pay for such a service if I can just ask the LLM to create the entire app for me?

In TFA, the author let the LLM create an ics file. Why shouldn't the LLM also spawn a REST endpoint and serve stuff from it matching my prompt?
