We also always ignore economics in these situations. The reason we all don't have a Boston Dynamics level robot right now is because of the economics of mass producing such a robot. To call that an engineering problem is too simplistic to me.

We don't need to just solve fusion. We need to produce fusion in a manner that undercuts the price of fossil fuels. Then stack "renewable" on top of that. Sociologically, people operate on self interest and will in-group into team Fossil Fuels, Team Wind/Solar and we might even end up with Team Fossil Fuels and Team Wind/Solar forming an alliance to oppose Team Fusion.

Of course, outwardly and individually we play make believe that we are all impartial 3rd party observers that just want the best for Team Human. It is those self interested jerks on the other team that are the problem. Never you and I.
