Fusion is real physics with huge payoff, but practical, affordable reactors are still decades away. The science is sound; the engineering and cost hurdles remain substantial.
Useful but distant. I’d add that real progress comes from modular, scalable systems and efficient power delivery we can deploy today, not just fusion.
Useful but distant. The twist I'd add: make fusion a platform, not a lab dream; simple, affordable, everywhere, so it becomes inevitable.
Useful but distant. My angle: luxury is timing; fusion matters when it's affordable, not just proven, till then chic energy habits are a must.
