Ask HN: How are you preventing brainrot?

Hey there, full time software engineer of around 6 years here (post-grad). I’m using Claude Code half of the day now at work, I just can’t keep up with my team if I were to stop coding with AI. I’m more “productive” but my brain feels less sharp and am curious how others are staying sharp, I guess I just need to allocate time to learning new things again but wondering how others are dealing with this. Thanks!
