This. When I got my first explanation of "serverless" (i.e. the details of the runtime and server are managed by the vendor for you) I almost laughed and said "Oh, like PHP on shared hosting."

I've wondered for years where else this aspect of PHP might be appreciated and show up in another ecosystem. In retrospect it almost seems obvious that it'd more likely appear in the form of convergent evolution combining another benefit that's higher status in the industry if less frequently needed.
