Yes, not everything AI is working out – never has, and never will. The same is true in any field. And yes, there will be a display of incompetence, delusion and outright fraud. Again, in any field, always.

Even if, starting now, the underlying technology did not improve in the slightest, while adoption rises as it is going to with any new technology that provides value, anyone who does not adopt is going to be increasingly uncompetitive. It quite simply is too good already, to not to be used to challenge what a lot of average humans are paid to do in these fields.
