The first 200 lines were never the hard part
Saw this thread from @paoloanzn doing the rounds and it nails something I’ve been chewing on. vibecoder asks claude code to build a chat app, gets a working prototype in 20 minutes, immediately tweets “just killed slack and discord”… brother you don’t even know what a distributed system is. you don’t know what database replication means. you have no idea how websocket connections behave at scale or what happens when 50k people are online at once and someone’s message needs to show up in 200ms across 3 continents
