The NIF is using old laser technology. Current tech can get above 20% efficiency. Sure, that still means more improvement is needed, but 200x is probably an overstatement by an order of magnitude.

> So we might be as close as 10-20 years away, as always!

I don't really get the cynicism here. This is a huge milestone that's been passed. Maybe with this, we actually will be 10-20 years away. Or maybe it's more like 30-40, who knows. But this experiment shows that net-positive energy is actually possible to do with our current understanding and technology; before this, I believe much of the skepticism was based on a belief that it may not actually be possible to get more energy out than put in, at least not without technology that's significantly out of reach.
