Interesting post from John Carvalho. A lot of seemingly simple topics, that are actually quite complex, covered. IMHO he gets more right than wrong.
What is very interesting is that ed25519 keys which are git keys or ssh key can do everything that nostr can do, and more. They can post stuff to lots of servers, relay stuff, integrate with most major tooling, and so on -- if they choose that.
But nostr can do one thing that pubky cant, and that is native integration with bitcoin time chain, distributed ledger and smart contracts. However this feature is still unused, and might never be used.
So in theory pubky could offer some significant innovation along slde nostr. I hope it goes well for them, as I like John, and it's good for users to have more options, and more innovation in the space.
