In any case it's a pretty silly contrivance, how about the oil age? or the silicon age? Both of those are likely to remain more impactful than the LK-99 age, in the event that it does turn out to be an ambient temp/pressure superconductor.
Alright, but if we're going to be relying on the authority of historians, they don't recognize the LK-99 age anymore then they recognize the steel, plastics/petroleum products, or silicon age though.
I can't speak for anyone else but what struck me as off about it was that it felt like boosterism for a technology that's so new and poorly understood it that we may find out it doesn't actually work at any moment. Even if it does work, we have no idea if it's useful in real applications or if it needs another decade of refinement. It reminded me of AI and cryptoasset evangelism, and made me inwardly groan, "here we go again...."
You don't have to write comments according to my preferences, I didn't downvote your comment fwiw, that's just how I saw it.
