Those three dots are omitting the most important part of the issue if we spend that much extra money on R&D
In the fusion case no one was willing to spend the money, in AGI's case it looks like everyone seems to be willing to spend the money.
I personally hope they won't, but that is a crutial point not to be overlooked.
