True, but on the other hand a lot of articles have been overly pessimistic about NIF's distance from Qtotal. They point out how inefficient the lasers are, while ignoring that NIF's lasers are old, and equivalent modern lasers are about 40 times more efficient.

There's no getting around that fusion research is pretty expensive. The payoff could be huge though. At this point it might actually be private funding that puts us over the top. CFS for example has about a billion in private funding, to do the same thing as ITER in a much smaller package, using better superconductors.
