I love to follow this field because the engineers working on tokamaks/stellarators/other fusion devices are dealing with some truly extreme technical challenges. However, creating devices that economically overcome those challenges at scale seems unlikely when solar panels and batteries are aggressively decreasing in cost. How will these compete if scientists figure out the longevity problem for perovskite solar? Just my opinion as a layman. I still think the research is worthwhile because of possible future applications (space?)
