The actual concept of a centralised entity competing against a global community to build an "everything" app is laughable.
We already have a NOSTR twitter
We already have a NOSTR Instagram
We already have other app services on NOSTR
Extrapolate the timeline of this and it becomes clear that more apps will be built on NOSTR than Elon or any central entity could build on twitter or China's WeChat. They simply cannot keep pace with the global community of builders.
Sooner or later, NOSTR apps will begin to merge into multi-functional apps and eventually an "everything" app.
Game over for centralised entities. Dawn of a new era.
