They specifically mentioned technological leaps, so that's what I went on, for better or worse.

I think clean energy will not by itself solve much. We need to reduce and reorganize at the same time as bringing on clean energy production, but that won't happen. Look at China, who is the world leader in clean energy production. I worry if fusion ever happens, people will just be like "great, electrical energy is free now", which won't be good.

I agree we need leaders thinking more than a few years ahead.
