If you run a buggy program on a modern OS, it won't crash the system or impact other processes. If you run a buggy program on DOS, it will write to random physical addresses, probably clobbering the state of other processes and of DOS.

Modern OSes can run arbitrary binaries, but they can pretty much run arbitrary non-adversarial binaries - problematic binaries have to be intentionally written to exploit the system (as opposed to DOS, where non-problematic binaries had to be intentionally written to not break the system).

It's a dramatic improvement.

It doesn't matter what OS I run. My "modern", and apparently buggy, CPU runs arbitrary systems that I know very little about, and I have little to no control over.

Since 2008, it's been a dramatic departure.

Mostly. Modern OSes strive to run abdersarial binaries, but where they can do it safely or not is still in question, IMO.
