He also didn’t mean to write known to be shitty, slow code, and yet, we have an entire communities of programming paradigms that argue you should do just that, arguing that “premature optimization” is anything that “doesn’t feel fast enough”. What is the definition of “fast enough”? It’s impossible to tell because for those exact same people, they got their guns cocked and ready to fire a “HArDWarE is ChEApER tHAn DEvEloPErs TiMe!!!!!1!1!1!1!1!!” At you the moment you suggest that maybe needing an entire 32 core Xeon server with a tb of ram to serve 20 requests a second is MAYBE in need of optimization.
