They needed private IP ranges that wouldn't conflict with the real internet. 192.168 was just sitting there unused, so they grabbed it along with 10.x.x.x and 172.16-31.x.x.

Modern apps are way more complex than Quake. Dropbox needs threads for syncing files, watching folders, updating UI, etc. Steam's web helper is basically running a mini-browser.

Back in the Quake days, we had single-core CPUs and tiny RAM - every thread mattered. Now with 16+ cores and tons of memory, it's cheaper to just spawn threads for everything rather than write complex single-threaded code.

Your computer's fine - this is just how software works now. We traded elegance for "throw hardware at the problem."

thank you very much!

pretty good!
