Almost certainly, the pop press is missing every possible “but”. Just from what I do understand, how impressive this is depends on the temperature and density of that plasma and annoyingly, they actually do mention that, but then don’t give the corresponding numbers.
I found a bunch of headlines saying the record for a tokamak is 22 minutes, which was impressive for beating the previous record by 25%. Progress in this tends to be incremental. Here’s a nice little graph of energy*confinement time from The Future of Fusion Energy:
This isn’t to say that the research isn’t great, either. I don’t think they’d bother if it was useless. And per the diagram they’ve had to do more and more with less funding since 2000.

Thank you for the informative and thoughtful comment. I appreciate it.
Hey, no problem!
