I agree with you but are we sure this ignition thing has proven we can use fusion for energy? Or was the key step towards it?

I’m guessing the Wright Brothers (and the equivalent of media/intellectuals at the time) didn’t know they had a sure thing early on either.

Usually these “tipping points” are defined in retrospect aren’t they?

That's why the premise of this article is ridiculous.

Agreed. It's only a useful devils-advocate type position. Something journalists love doing to generate clicks.

Sure. But watching a bird fly is a key step towards making a 747 too.

The energy that came out of the fusion reaction was more than the energy in the laser beam that ignited it. But the energy that went into the laser was about 100 times more than the energy that came out, so we've gone from -99.5% efficiency to -98.5% or something like that. Is that a key step? I suppose. Is it major progress? Maybe. Does it get us substantially closer to practical fusion? No. Not by a long shot.

Yes. Exactly. So then why is the article trying to define them?
