For me personally, holding a dialogue with several agentic dev streams in parallel keeps me very much on my toes mentally. It's quite exhausting, and certainly not letting my brain atrophy.

I'm probably losing some coding skills, but replacing them with different ones, and honing some others.

I used to manage dev teams of 20+ people inside high pressure, high stakes projects.

I've been coding all my adult life, on big things and small.

To me, agentic engineering is a deja vue of managing teams, except in real time.
