I think the parallel between cost of semiconductor fabs increasing and costs of fusion reactors increasing is quite apt.

But we don't actually have exponential improvement in any physical object, that's not to do with information processing - a solar panel or battery made today is not 10x better than one made 10 years ago.

It's not even true of all semiconductors - power electronics, radio, etc.

Do you understand how differently that reads from your original comment?

> Fusion has advanced faster than Moore's law - and unlike the holy grail of computing, true AI, it's now clearly within reach.

You made the claim it's advancing at a rapid rate and almost here, and when someone pulled up the data it wildly disagreed with you. Now you're just moving the goalposts.

Thank you. I was thinking if his initial post meant something else. Or I was misunderstanding his replies.
