> imo audio DSP experts are diametrically opposed to AI on moral grounds.

Can you elaborate on this point? I don't know the moral grounds of audio DSP experts, and thus I don't understand why in your opinion they wouldn't take an offer if you really pay them some serious amount of money.

Just to be clear: considering what a typical daily job in DSP programming is like, I can imagine that many audio DSP experts are not the best culture fit for AI companies, but this doesn't have anything to do with morality.
