> How to tell people you have never implemented anything performance sensitive in your life without spelling it out bluntly in a nutshell

And that’s okay. Millions of engineers work on software that leverages those fine-tuned optimizations. Hundreds of engineers make them.

Plus I grew up in an era of cheap compute. Everything got faster every 18 months for free. Even now computers as a whole keep getting faster and faster despite the cap on single core performance.

Even at my relatively high level, the performance concerns I spent months learning about in 2005, just don’t matter anymore when you can get a single server with terabytes of ram and petaflops of compute.

99% of [user facing] code just isn’t performance bound these days. What does it matter if your loop takes 10ms or 20ms when the data is a 300ms network call away
