One thing that’s new, according to the New York Times, is massive investment in R&D by the government of China. Meanwhile in the U.S., it’s more about startups and public-private partnerships. In at least one anecdotal case mentioned in the article, top scientists from China who have been based at top U.S. universities for decades are choosing to go home. The article suggests that American firms are often the first to achieve breakthroughs, but the Chinese system is better at scaling and commercializing them.

It seems like there is an opportunity to cooperate for the greater good here, no? That is not the way the political winds are blowing at the moment, of course. At least in this case, if our countries aren’t actually cooperating, they are not competing to weaponize the technology first. This technology was weaponized more than half a century ago, of course, and the quest ever since has been to learn how to control it for peaceful purposes. Of course, the joke is always that commercial fusion is two decades away, no matter what decade we are currently in. This article declines to give a clear time table for widespread commercialization, but it talks about a “pilot plant in the 2030s and 2040s”, so yep the rolling two decade projection seems to be holding.
