His videos about functional programming are amazing (Mark Seemann). "Pit of success" is one of the best. [VIDEO]

I spend a lot of time thinking about these sorts of topics (actually, I just taught a 4 hour session yesterday that used most of the terms in this article), working with newer, less experienced developers, and trying to figure how to distill the essence of "architecture" down to something simple that everyone can start with. This is what I’ve started telling people: Use mostly functions, try to make most of them pure. I think that can get people (even new devs) 80% of the benefits (testability, composability, loose coupling, and the ability to reason about code) of more complicated, prescriptive architectures (Hexagonal, Onion, Ports & Adapters, Clean, etc) with a minimal amount of ramp up. Of course, this isn't the solution to every problem (it obviously depends on the domain you are working in, for me its webDev and backends), but I think maybe its a good way for people to start. Edit: Here is a great talk demonstrating that by following a simple functional approach, your code can naturally fall into a “pit of success”: [VIDEO]

"pit of success" from the previous comment might refer to this video, which is long but good especially to adjust to a different mindset [VIDEO]
