The comment above probably meant to say that any environment becomes "serverless" as soon as you stop managing instances/servers manually and interact with it strictly via an API endpoint, which of course has always been possible but required fairly in-depth knowledge of AWS APIs (or other cloud provider's).

Look, there's nothing dirty about re-framing the conversation every once in a while. It may feel like BS at first but over time we attach new meaning to old words and it becomes easier to communicate capabilities.
