AI strategy isn't about replacing people. It's about augmenting them.

Most companies get this wrong. They try to automate everything instead of finding the high-leverage workflows where AI can be a co-pilot.

The biggest mistake leadership makes with AI? Treating it like a headcount reduction tool. I was talking with a CTO yesterday who realized their "automate everything" strategy was actually reducing output quality. Why? They removed the human taste-maker from the loop. AI isn't here to replace your team. It's leverage, not a layoff plan.

Stop using AI to replace your team. Start using it to give them leverage. The goal isn't "how do we reduce headcount?" It's "how do we dramatically increase output quality?" Co-pilot. Not autopilot.

hot take: if your AI strategy is "how do we fire people?" you're doing it wrong. it's about giving your best people leverage to do impossible things.
