My very uninformed opinion (nuclear physicist by training, but not specialized in fusion, lasers, or plasma physics) is that we’re still 20 years (haha) away from fusion energy making its way into the power grid. And that is assuming this result (or other things, like the relative instability of global energy markets lately) causes an increase in funding for the field so that they can solve all the pesky engineering issues related to efficiency, reactor lifespan, reliability, cycling speed, etc.
