Well, yeah, I agree with that.
But I’d argue that it draws from the same limited funding pool as renewables and other climate-important research.
The latter is urgent. We may not get to the point of effectively utilizing fusion unless we stabilize the planet, and the damage would be priceless. So if we have to trade one for the other, I’d say the bulk of funding should be diverted away from fusion and towards faster solutions, ones more immediately cost competitive with oil.
It’s not that we shouldn’t research it, eventually. There’s lots of long horizon concerns. But factoring in the time horizon is very important, and reducing emissions is needed yesterday.
