It is somewhat baffling that most interactive, consumer-facing operating systems are not real-time. I suppose that it’s a product of legacy and technical debt.
Apple did announce that they’re using an RTOS in the Vision Pro. Maybe the VR/AR space will make this more common, since the latency requirements are more stringent.
@verdare @lysdexic they are, but you have to be an enterprise customer.

RTOS are not going to become consumer operating systems, because there's too much value in selling it as a capability to enterprise customers (who are largely the consumers who REQUIRE a RTOS, rather than it merely being a convenience).
How can it be convenient for the desktop user to severely limit the amount or running processes? Desktop usage scenarios are the opposite of RT usage.
