I don’t get it, tech people clearly have the most to gain from AI like Claude Code.

Computer code is highly deterministic. This allows it to be tested fairly easily. Unfortunately, code productionn is not the only use-case for AI.

Most things in life are not as well defined --- a matter of judgment.

AI is being applied in lots of real world cases where judgment is required to interpret results. For example, "Does this patient have cancer". And it is fairly easy to show that AI's judgment can be highly suspect. There are often legal implications for poor judgment --- i.e. medical malpractice.

Maybe you can argue that this is a mis-application of AI --- and I don't necessarily disagree --- but the point is, once the legal system makes this abundantly clear, the practical business case for AI is going to be severely reduced if humans still have to vet the results in every case.
