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."
