I'd add one point to this, as someone who voraciously fights against complexity t every turn, more and more as I get older. I've experienced times where leadership/management will assume that you're fighting against the complex solution simply because you don't grasp or understand it. It's irritating at best.

The longest lived projects and solutions I've worked on have always been the simplest, easiest to replace solutions. Often derived from simple tests scenarios or solutions that just work and get shifted over without much re-work.

What's somewhat funny, with this is that AI code assistants have actually helped a lot with continuing this approach for me... I can create a stand alone solution to work on a library or component, work through the problems, then copy the component/library into the actual work project it was for. I'm in a really locked down internalized environment, so using AI for component dev is on my own hardware... but the resulting work is a piece that can be brought in as-is. No exposure of internal data/resources.

I don't think I'll have a level of trust to "one-shot" or vibe code solutions from AI, but leveraging the ability to spin up a project as a sample to test a component/library is pretty great to say the least.
