It's not struggling. It's a time preference thing. The same argument has been talked about Bitcoin. "It's old tech" "It's too slow" "There's faster versions that do better things" 

For me Nostr is doing a job and doing it well. This is the problem with transitioning from a consumerist economy to a sound money economy.  The mindset is "now, now, now" and that doesn't build quality - it builds quantity. Which will eventually offer nothing productive, and break society.
