The problem is urgency and we don't have an enough amount of uncertainty budget to chase fusion reactors. The scale of the problem is so huge that even Bill's fortune could be insufficient to make a dent to the problem in a foreseeable future. Yes, it'd be nice if Bill can make it happen but if not, he's going to regret it. I'm pretty sure that Bill already has done the math, concluded that we probably have only less than 10 years and next-gen nuclear fission reactor is the only feasible mid-term technology to fight against climate change.
