I never used Erlang, and I'm a functional programming fan. But languages based on heavy VM that abstract OS away always make me doubt that's the right direction.

That's not a crazy instinct, and maybe if OSs were better you would even be right, but there's not really another way to get a skrillion communicating processes that can all crash/fail independently. Without a dedicated VM, all the other approaches are either less safe or too inefficient.

I consider BEAM an indication of a direction that OSs could and maybe should move. It's even possible to run BEAM on bare metal, (almost?) entirely in place of the normal OS.

Using GRiSP Metal, not exactly without an OS, but using a real time OS designed for embedded devices.
