That guy is a moron.

But AI assistance in taxes is also being introduced where I live (Spain which is currently being government by a coalition of socialist parties).

Still not deployed so I couldn’t say how it will work. But preliminary info seems promising. They are going to use a publicly trained AI project that has already being released.

The thing is that I don’t think that precisely that is a Musk idea. It’s something that have been probably been talked about various tax agencies in the world in the latest years. The probably is just parroting the idea and giving them project to one of his billionaire friends.
