Agree with most of what you said except for the "big bucks" part. Why would I pay for your product when I can ask the AI to do it? To be honest I think I would rather use that money for anything else if I can spend a little bit of time and get the AI to do it. This is quite deflationary for programming in general and inflationary for domains not disrupted all else being equal. There's a point where Jevon's Paradox fails - after all there's only so much software most normal people want and at that point tech workers value relative to other sectors will decline assuming unequal disruption.

The ability to earn the big bucks as you state is not a function of the value delivered/produced, but the scarcity and difficulty in acquiring said value. That is capitalism. An extreme example is clear air that we breathe - it is currently free, but extremely valuable to most living things. If we made it scarce (e.g. pollution) eventually people would start charging for it; potentially at extortionary prices depending on how rare it becomes.

The only exception I see is if the software encodes a domain that isn't as accessible to people and is kept secret/under wraps, has natural protections (e.g. a government system that is mandatory to use), or is complex and still requires co-ordination and understanding. This does happen, but then I would argue the value is in the adjacent domain knowledge - not in the software itself.

In fact, in many spa towns you have already local taxes, e.g. "climate surcharge" where you actually pay as a tourist for the clean air. Usually it's a local tax that is added on top of your hotel bill.
