It was unclear to me that you were being tongue-in-cheek. Were you serious, I'd point out for starters that A. You probably don't know whether it's serverless currently and B. Even if it were it's not a particularly uniquely likely explanation for consistent latency at scale
Severless often gets touted as being the best way of doing things rather than just a way. My comment was a dig at that.
But it seems like my comment somehow exposes multiple levels of ignorance, would love to know what they all are!
