It looks like course details are linked in the sidebar to the right:

(perhaps this URL would have made more sense for submission, per "Please submit the original source"?)
VT-x is not a RISC-V feature, it is a feature of x86 cpus, which is definitely not deprecated. VT-x is (as far as I know) the technology that allows acceptable speed virtualization of virtual machines, which is the backbone of cloud computing. RISC-V H extension is not applicable to intel CPUs even if it provides features that solve similar problems (ie it cannot possibly be the replacement).
Unfortunately no mention of V86 even in the intro/history section, which could be considered the origins of x86 virtualisation technology, and achieved widespread use starting with Windows/386 and all the way through the Win9x lineage. If you've ever used those versions of Windows, you've used a hypervisor.
Anyone who enabled WSL2 was also running Windows under Hyper-V so that Linux could run at the same level. (The same thing virtualization-based security uses.)
