Oh no.
Are you aware that the majority of cpus sold today go to cloud computing? Believe it or not, but that is an application space with multiple users on the same machine.
Good point. But I think performance is still a greater priority for those who make purchasing decisions, rather than basic security, and that’s the problem.
Not at the enterprise level.
Security means compliance, which means getting/keeping contracts and not getting sued.
And they care more about performance-per-watt and density.
Even on a single user machine, multiple users are very much a thing. Even Apple has left behind the DOS-like architecture where everything runs with the same rights. All current systems run with multiple concurrent users, notably root (or the Windows equivalent) and the keyboard operator (as well as dedicated ones for the various services, although that’s maybe more a thing in Unix/Linux than Windows).
