> 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. 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.
