I was interested in Vagrant when it came out, but it was a touch too early in my career. I still don't really understand why it exists or what problem it solves.
I think it was big for easy local dev setups in a VM. But I think docker has pretty much taken over a lot of those use cases since a build can happen in a container pretty trivially across platforms these days. Plus be ready to deploy with the same tools, which Vagrant didn't cover.
Nobody knows. They don't know either. They're terrified that someone will figure it all out and they'll have to pay back all that VC money. Hence the current crisis.
