Not really following too closely, because 1) it is just an incremental step towards fusion, and 2) all the discussions have been professionals talking to professionals rather than laymen. Having said that:

Are they discussing “greater energy output than input” in terms of measurement, or useful energy production? I mean, they can do the first in terms of using fission to produce fusion, but the only practical use is making large explosions for warfare. (Limited usefulness.) Or are they at the stage of recovering energy for self sustaining energy production?
