I'm old, fusion has been close for decades. Some reactors achieve unity but can't sustain, some can sustain the plasma but don't quite produce a net energy production, and all of them are limited by selection of materials compatible with the sheer radiation of the chamber.

We're frustratingly close, and progress has been made, but I get the feeling it's one of those areas of science where a large breakthrough in either MHD theory or material science is needed to kick fusion from info NG research into practically possible.
