Describing progress as lines of finite length, I guess is true. But they are pretty long lines. Eric has assured me that once a commercially viable device has been produced; research will continue. I can envision teams of engineers and scientists working well into the future to make these generators: smaller, lighter, cheaper, more durable, easier to service. Perhaps different variants of the aforementioned characteristics for special settings.

Neutrons aren’t always bad things. We need an ongoing supply of radioisotopes for research and medicine. If we can produce these in Focus Fusion generators, we should. Making it easier to avoid the other F-word (fission).
