I hear a lot of worry, from energy analysts, about the risks of neglecting to install and scale up replacements for fossil fuels, in time for “The End”. As yet, they are skeptical of the ultimate feasibility of fusion.
Building the infrastructure while there is still time is a REALLY good idea. Our “oil lords” try to protect their future, but they don’t have to pick up the pieces. If there are 75yrs remaining for fossil fuels, then that’s beyond the life time of anyone currently in charge, so we cant count on them to install replacement infrastructure.
