Was hoping this comment would be here. Firecracker and microVMs are good use-case. Also, being able to simply test and develop is a nice to have.

Nested virtualization can mean a lot of things. Not just full VMs.

Good use-case for what?

Nowadays universal answer for "what? why?" is AI. AI agent needs VMs to run generated code in sandbox as they can not be trusted.

I don't think everyone should assume that AI is the answer to all questions. I was asking the person I replied to, thanks.
