Counterpoint to that though: "Serverless" isn't all that much "easier" to setup compared to traditional server setup. You still need to know how to wireup your request gateway to the correct service, you need to write your app for a serverless setup, setup security groups, etc. None of that is particularly "accessible" for someone trying to get running ASAP.
I agree tech is getting democratised, but when talking about products that allows it, I'm thinking of products like Firebase or the recent darklang, not AWS Lambda. From all the Lambda usage that I've encountered so far, they are still very much in the domain of a "sysadmin".
