Maybe it's being done on a server, but maybe it's a magical genie in a bottle. You don't have to care because from your point of view you upload code and that code magically runs.

Hard disagree. As someone who wrote several AWS lambdas, I know you have to care that it's being run on a server and you have to adjust to your code to work within that very-specific server system.

If anything it should be called "poly-server" because you cannot write your code without considering that it can be executed from several servers around the same time. I don't buy what you're selling here, other -less examples don't seem to betray their terminology at all to me but "serverless" will always sound wrong to me.
