Hyper-V runs as a Windows Server role. Windows kernel is C, and assembly
gVisor runs on Linux -> C, assembly
Firecracker runs on KVM, which runs on Linux -> C, assembly
In every single thing you have listed, the closest thing to the "bare metal" is C, and assembly. THAT's what makes C special. Its level of adoption, ubiquity and accessibility. Not its spectacular lack of security risks.
Anyway, you have come a very long way from where the parent poster started which was:
Most of the stuff people think of as being the "metal" in
C are, in many cases, virtual abstractions created by the
operating system.
To which I merely pointed out, on the other side of the interface layer is, most commonly C. And assembly.
Operating Systems design has to and is obviously evolving away from this. I disagree that we have reached "peak C" and that is going to decline before it gets bigger.
Unfortunately pjmlp many of the conversations we have start this way, and devolve into this. I don't think I'm going to bother again. I think one (or both) of us will just have to agree to disagree. Have a nice day.
So ... you're repeating what I already said.
Android -> Linux -> mostly C, and assembly
IOS -> Darwin -> XNU -> C/C++, and assembly
