Most of us don't understand what we don't understand.
If a shill pushes AI FUD we may endorse or refute that shill without recognizing that we don't ourselves understand a register machine, basic computation and networking, symbolic language, without all of which, even a basic general descriptive level appreciation of "AI" is impossible.
For this reason the subject of "AI" has been a favorite of NPCs, but the domain of experts and imposters.
