But is that impossible, I don't think so. I'm not going to say we're 10 years away from it being viable because we've been 10 years away for the past 50 years. But look at how fast every other technology evolves, this is literally the beginning for where it all starts coming together. I'd bet people alive today will see fusion energy become a reality.

Ya OP didn't word that well. IIRC the laser put around 2MJ on target and the resulting fusion yield about 3MJ, so if NIFs laser was more efficient than what OP said would be accurate. But in actuality it took the NIF laser something like 200-300MJ for that shot. But when you consider that NIF is getting relatively old and that it's a research center so efficency wasn't at the forefront of design it's not unreasonable to see where this could hopefully lead.
