> why is the UI so slow / explorer slow / bluetooth slow

this is a legitimate complaint, but I see latency absolutely everywhere. my iPhone 17 Pro dropped frames out of the box . now 3/4 unlocks drops frames.

I'm not defending Windows, it's obviously in decline -- but trying to identify root cause. There used to be curmudgeon engineers on staff who would berate team members over blocked UIs, dropped frames, input latency over 30ms . Dave Cutler made a rubber stamp that rejected (then paper) code reviews with "Size is the Goal". That culture has retired.

Web-dev's design interactions targeting 500-2000ms, so to them everything on the OS looks fast . Adding 150ms to right-click is unnoticeable . Like 15kHz audio to a boomer or purple to the color blind .

It's easy to beat up on MS, because most open-source devs have despised them. But Microsoft had a very high bar for engineering until about 10 years ago ( you may laugh, but remember they were writing OS's that last 40+ years) . Apple had an extremely high bar until about 5 years ago.

This isn't just one bad product, but an entire industry lowering its standards.
