Look, for most websites renting less than a handful of dedicated boxes would be enough for all purposes -- dev, staging, production. Instead they rack up an astonishing cloud bill from Amazon.

You are not. I am only 38 and I only work professionally as a programmer for 16.5 years but I am already quite conservative in terms of ruthlessly eliminating complexity and removing any tech that can be consolidated in a monolith repo without huge amounts of effort.
Experience helps a lot. When you know that complexity and too much diversity breeds tech debt, you learn to say "No" decisively.
