The first time I heard the term wireless, I was a little kid and I understood very quickly. When I first heard the term “serverless” I was an adult who had been programming a couple years. I remember genuinely being confused as strings of unparseable buzzwords bounced off my brain. A minute or two into the explanation, I’m pretty sure I said “oh, so it actually does run on a server”. The ops person was forced to say yes. It was a genuinely confusing and imo pointless conversation that we shouldn’t have needed to have.
