I'm not sure I'm following your thought on capital gains tax.
Capital Gain tax occurs when you sell an asset for more than you paid for it.
AI (software) is not an asset, and I'm not sure how you'd sell it. Computers and robots are assets (although they typically depreciate not appreciate.)
Either way capital gains tax is applied to the asset not the productivity of the asset. The productivity in turn is taxed as part of income tax.
Perhaps I have misunderstood your point though?
The ownership of software absolutely is an asset. It’s Intellectual Property. What are you referring to?
If your brokerage account is large enough that most of your change-in-net-worth happens in unrealized capital gains, your tax rate is 0%. That's pathological at the best of times and in a "capital wins" scenario it's positively thermonuclear.
