This is nonsense. Old software was not fast. Computers used to take minutes to start up. That’s not an exaggeration. MS Word could easily take 30 seconds to open.
Obviously if you run it on modern hardware it’s going to be lightning fast, but not because the authors cared more about performance and efficiency than we do now.
They’re not lying, they’re exaggerating. Obviously coding isn’t solved but I don’t think the fact that that is an exaggeration is going to save our jobs from becoming agent wranglers sooner or later.
I’m not happy about it but I’m not going to stick my head in the sand and pretend it isn’t happening either.
