Yep. And video games. And media decoding. And a whole bunch of other stuff
that interacts with physics including the time dimension.

I disagree. As I've said before, cell phones are extremely real-time
devices, to the point of needing to know the temperature so they can adjust
for how much that makes their quartz crystal drift.
You're not going to want a GC cycle to interrupt your playback of your CD,
either. Etc.
When your machine has 5x the power it would need to do the job with
dedicated software from the ground up, it's easy to load a 3x overhead
factor in the form of a general purpose OS and still get it working OK.
