I cannot agree more, and this is coming from a young whipper-snapper that tries to stay on the leading edge of technology.

There's a vast tectonic shift occurring and it couldn't come sooner -- "tinkering" with an increasingly complex environment of microservices, message queues, RPC servers, databases, caches, and so forth is headache-inducing and everybody knows it, as it detracts from actual application development.

I like the nest of snakes analogy, it's quite accurate. The twelve-factor application architecture[1] is here and many are moving towards it in one way or another, be it simply starting out writing unit tests or refactoring large applications into something easier to grok.
