It seems that for the last couple decades fusion is always 30 years away and by this point we’ve well passed the initial 30 and seemingly little progress has been made.
Is it just that it’s so difficult to make efficient?
Has the technology improved substantially and we just don’t hear about it often?

One issue that is not really spoken about is that the supply of tritium is insufficient to sustain all of the planned experiments, so there will be a bit of a crunch soon. You can breed it using lithium blankets but we still need to have it produced by nuclear reactors and there aren’t enough to sustain a fusion industry at the moment.
