It's not about whether abstractions exist, it's about whether the jargon for them requires remembering long lists of services from index cards so you equate "AWS Fargate" with "AWS Serverless Containers" and having the certification training teach you to say the whole stack that way so nobody but AWS certified people know what the hell you've proposed or built is.

I've built plenty of things with AWS and a lot of the technology is quite good, but it's not about that.
