I don't know. Looking closely at the article reveals that the researchers achieved 1.2x energy gain from the lasers, which are about 1% efficient. Given the SOTA for such lasers is closer to 20% efficiency, this means that they achieved about 60% of break-even. But that's energy, no electricity. Even with the best current methods, about 60% efficiency is the best we can hope for in terms of getting actual electricity from this. So in practical terms they achieved 30% of break-even.

Is that good progress? I'd say so, for sure. Is this a breakthrough? I don't know, especially since the article itself says the data is still being analysed and the actual results aren't published yet. 95% of the article is just fluff about the potential and quoting 3rd parties who celebrate a result that hasn't even been officially confirmed yet.

So, no I don't think it's cynicism, I don't think it's contrarianism, and I do think it's VERY healthy to approach sensationalist headlines with a level-headed and down to Earth attitude instead.
