Perhaps I am just optimistic but AI doesn't seem necessary, nor does fusion. Fission is more than capable of providing enough power and if we are going to do this via sequestration, we may as well start now and forget net-zero.
I definitely think this is an organisation problem, not a technology problem. Societies are not organising to fix the issue, instead it seems they are hoping the global free market will eventually make it economically beneficial in the short term, to save the climate.
There is plenty of data that suggests societies respond to financial incentives.
As the cost of battery/wind/solar plunge, their use goes up. And fusion has the potential to be much cheaper than those.
A very very small percentage of CO2 emissions is due to people wanting to increase CO2 in the atmosphere. Almost all of it is because that is the cheapest or most efficient way to travel, heat your home, make products, etc...
