Probably, if "future" means 50+ years, so two generations in future.

But not if it means "future" in even overlapping the current nuclear plants that are EOL, 10, 20 even 30 years. Because to replace those nuclear EOL with other nuclear, we'd need to start building plants in 2014, 2015 (which we didn't). The next best time may be now, but "We", at least in Europe aren't doing that either, and AFAIK neither in the US.

TBC: I'm not saying "it won't work, so stop chasing it" on contrary. But shoehorning "fission" into a discussion of a current energy crisis, what this article is about, isn't relevant. Such tech isn't for today, tomorrow. Not even for when your kids grow, up, but at most for your grandkids when they are working - horizons.
