>Yes, universally. And no, not a bit. It's 10-100x across varying components. Look no further than MS Teams.

Universal latency regression is a ridiculous claim. For one, 20 years ago it was common to have 1-5 minutes loading time for professional software, I spent way too much time staring at splash screens. Can you imagine a splash screen on a music player? It was a thing too. Nowadays splash screens are nearly forgotten, because even big software starts in seconds. SSDs have nothing to do with it either, the startup reduction time trend started in mid-2000s by big content creation shops such as Adobe, precisely because people were fed up with long startup times and started complaining. Jerky mouse movements, random micro-lags due to hard disk activity and OS inability to schedule I/O properly, it definitely wasn't all smooth and lag-free as some people paint it. MS Teams is pretty much the epitome of bloat, counterpoint would be software like Zed, which is really fluid and optimized for latency, so it's already not universal. Software like MS Word was laggy then and is less laggy now. (and crashes a lot less these days)
