ChatGPT is like chat rooms on the internet at the beginning.

Obvious, but not the end point.

The first mass-market use cases of the internet were chat and email.

Everyone "gets it" immediately.

But that's not all there was in AOL.

As time went on, the value of all of the information at your finger tips grew, and then those experiences could be interactive applications.

The secondary use case of "teleport anywhere, do anything" was harder to explain, but could diffuse out as people used it.
