Let's see if it actually materializes. It's not hard to make such claims, it's much harder to deliver on them. I very much doubt the 5 year timeline from "net energy gain" (net plasma energy gain) to an actual power plant (actual net energy gain). Again, extracting energy from the plasma is mostly a theoretical idea at this time, and all the proposed mechanisms would likely require significant engineering challenges (the biggest temperature differential in the solar system; neutron bombardment).
