When I was new and coding was slow, my worries were about so many other things (like how the language even worked) than even what text editor I used, let alone the monitor.

As I became experienced, a lot of newbie problems went away and the next topmost problems emerged, leading to be obsessing over text editor, shortcuts, and even a multi-monitor setup with a vertical monitor.

Then went through a minimalism phase where I was annoyed by how much time I was spending maintaining my tools rather than using them, so gone went almost all of that. Just one giant monitor and VSCode for better or worse (mainly because it does all six languages I use well enough).

I'm now at a phase of thinking, "who are all these people who do so much coding in a day that these things matter?" because reading and writing code is maybe.... 35% of my job now? What I need to optimize for is reading/writing human text. And that's where I currently am: figuring out how to optimize writing documentation/design/architecture docs, given how awful making and maintaining a sequence or block diagram is currently.

My conclusion so far is that I expect my needs to continue to mutate. I do not believe they are "converging" and do not believe there is any sort of golden setup I will one day discover.
