That is absolutely true but that's similar to saying if you don't sling code, write your own scripts, and run Arch then you don't know shit about computers. Some people even grow and kill their own food.

For some people all they will want is a client that works and not a broke ass client. It's up to other people that do understand and specialize in computer related services to have the intent of making a better experience for others. Similar to someone that builds any project from the design of a paper airplane to a sensor in a satellite.

It takes a bunch of "NORMIES" to build an empire. NOSTR is just a piece.
