mind elaborating a bit?

He's probably mad because with serverless, there are servers. You just have no control over them. "Serverless" is just "shared hosting" reinvented...

There are still servers involved. Serverless sounds like its peer to peer. What it really is is VM less.

There's still a VM, too.

Can we call it "stateless"? Because there's theoretically no server state between requests?

Well, as a developer I don't need to concern myself with servers, so in a way the term is fitting.

The interface it gives you is the functionality that the server provides. A server does not mean 'operating system'. you don't have to deal with the OS, but you still have you app running on the server.
