PHP invented some kind of "serverless" before it was hype. Think about the PHP model for a minute. Share nothing. Each request is isolated from the previous ones. One script per endpoint. That's exactly what so called serverless platforms enable today. PHP had it in 1998! Last century. Simple, easy. Now, you need tens of layers to achieve the same. Not sure it's "better". I'm half-kidding here.
Don't want to use PHP just because some noisy people on Reddit/Twitter/... find it bad? Fine by me, I don't care. Business as usual.
