You are right.

However, it should be noted that more technical challenges will arise if and when Nostr becomes more popular, even mainstream.

> But whatever, I'm just saying this because every time someone finds a small bug on any Nostr app they complain and say Nostr is a failure that will never be able to compete with giant corporations or something.

They might be right, too, because Nostr has to work much better for people to actually use it.
