The more experienced the developer, the faster they are. The faster the technology enables you to be, the faster you'll produce something. Both go hand in hand.
An experienced developer would absolutely love Serverless for most problems they face. Having the option of doing as little Ops as possible and just solving problems in software is the very definition of a software developer (which certainly might be changing over time) :)
I still don't see where the savings of time come in. What you lose in "ops" you gain in configuration and assuming you don't have eidetic memory that has a time cost.
What configuration? I use AppEngine for a personal project I'm developing, and besides the app.yml file, which is about five lines long, I don't configure a thing. In fact, I don't even have to stand up databases to use one: I just make the API call to store the data and it's handled for me. Literally zero configuration.
That's in the standard environment. Even in the Flexible Environment the configuration is equally nonexistent.
Give AppEngine a try: I honestly believe you'll consider it the true definition of Serverless.
