distributed systems

I can't get rid of the concept of "logging into a node".
Is it possible to get rid of that idea?
I guess the abstraction of "this machine" is just a hard one to shake.

So what is a "machine" in that sense?  A CPU of course, but that is
just the thing that mixes information.  A machine is really its
connection to "devices".  That's what I need a ssh for.  To get to its
disk directly, or its USB ports etc..

For applications, most of that can be abstracted: what the CPU does in
that case is to abstract the local devices to participate in network

In that sense, a machine is a network endpoint.  A last hop router.
