Do you guys ever code without AI just to make sure you still can?

I use coding agents all the time now. Claude Code, Codex, etc. And tbh they’re insanely good. I’m definitely not in the “AI is ruining software” camp. But lately I’ve had this weird feeling. I’m shipping way faster, solving more stuff, touching areas I probably wouldn’t touch on my own… but I’m not sure I’m actually becoming a better engineer at the same rate. Stuff that used to force me to sit with docs, debug for an hour, think through the architecture, or just struggle with a problem now often turns into a conversation with an agent. Which is obviously great for productivity. But if you took AI away from me tomorrow, I feel like I’d get nerfed pretty hard. Not just in speed. Probably in confidence, recall, and raw problem solving too. And that kinda bothers me. I’ve been thinking about doing some no-AI coding sessions or an “AI detox” once or twice a week. Not because I want to stop using AI, but because I don’t want “being good at using AI” to slowly replace “being good at engineering.”

Do you intentionally practice anything without AI anymore? Or is worrying about skill atrophy basically nostalgia for an old way of working?
