This is where is becomes confusing to me: Here are a few types of software/infrastructure. Embedded devices. Operating systems. PC software. Mobile device software. Web frontends. GPU kernels. These all truly don't use servers. When I hear "serverless", I would think it is something like that. Yet, they're talking about web servers. So it feels like a deception, or something poorly named.

If you are in the niche of IT, servers, HTTP operations etc, I can see why the name would make sense, because in that domain, you are always working with servers, so the name describes an abstraction where their technical details are hidden.
