Yea very curious as well would need to dig a little deeper. If it's the beam energy it means we need more efficient lasers or to scale larger to overcome the energy losses from making a laser beam.
Still even if it's just the beam we are at an energy positive which is still great news because it mean the fundamentals are working.
Still other issues though, the biggest in my opinion are an effective way to produce Tritium and energy extraction.
Looks like the Nature article (https://www.nature.com/articles/d41586-022-04440-7) is more clear about it still being a net loss. Still an important step forward, but it's important to contextualize it.
