This is sort of like all new tech and domain application. The application tree first grows in breadth, then depth. I'm guessing real use cases will take 5-20 years to settle.
It’s like all new tech, if you fall into the survivorship bias trap and only look at the ones that have survived.
Personally I think this will be another “AI winter”, where we will gain some improvements in narrow domains but fall far short of what was promised, leading to disillusionment and a reduction in research budgets.
