What I find interesting is how rarely people in these discussions name the mechanism that makes going back hard. It's not just efficiency. There's a feedback loop built into AI coding tools that's genuinely dopaminergic: tight, fast reward cycles for each autocomplete hit. Taking three months off coding by hand is essentially a detox. The fact that the author framed it as a deliberate experiment rather than just "I prefer vim" tells you something. There's a piece at sloppish.com/dopamine-loop.html that gets into the behavioral design of these tools specifically.
