Linux

I mean, they’re not totally wrong if you’re just talking about overhead opening a “simple” app- however this falls apart when you’re talking about actually using the hardware- video encoding/decoding, file reading/writing, multitasking, real time event handling, random IO, etc etc etc. it’s also much less obvious in linux and macOS which boot apps extremely fast.

Modern software also does a lot more, at higher resolution, with more flexibility, etc…

Maybe notepad takes 5 seconds to load on some windows laptop vs 1 second on an 80s machine- but I also don’t just use a computer for notepad. The volume of data I crunch a day, while running docker containers and services and transcoding and compiling and rendering and transferring tons of IO is staggering even compared to 5 years ago.
