There are three options:
1. AI owned by everyone
2. No AI
3. AI owned by billionaires
If you can make the masses fight for 2 instead of 1, then you guarantee that you don't get 1. If instead, the masses fight for 1, they've got a chance of getting it. You present AI as a false dichotomy: no AI or AI for billionaires. But 2 is a fantasy. There will be AI.
Any of us arguing for (1) get shouted down by the very people who would benefit most from it. The masses do the job of the billionaires.
Most utopian science fiction has AI doing the work and humans leading a life of leisure (e.g. Culture novels). Dystopian futures have AI keeping the rabble under control (Neil Asher's Owner Trilogy, Elysium). Time to choose folks.
