I'd say most of the problem here is that viewpoints are meted out as simple pithy statements. Half of the comments on this thread are one sentence statements saying the building has 200x to go before it's truly net positive.

You get more content out of a discussion with your neighbor in 30s than that. Those comments are genuinely worthless, they don't talk about things like:

1) What are the parts of an inertial confinement fusion based system which are difficult and which are missing today and would need serious investment

2) What is the likelyhood that the power output observed here could double, or more with other scale factors?

3) What's the net system costs once a plant is made. Is the fuel cheap or expensive?

Etc. It's fine to be contrarian, but most of the contrariness on this most internet forums is of the most basic, shallow kind that is defeated in a moment by any serious thinking.

The short answer to being better? Posts with more in depth content. I seriously think HN should consider banning pithy one or two sentence posts "they still would only get 1/4 the power" you find all over the place.
