You described exactly what makes a PM irreplaceable:
Staying out of the way
Removing blockers
Shielding the team from politics
Enabling decisions instead of making them
AI can summarize status reports. It can't protect a team from a dysfunctional stakeholder at 2 a.m., or know when an engineer needs space vs. needs support.
The fact that you're even asking this question tells me you're not the problem. The terrible PMs never do.
Don't leave. Adapt. Learn the tech enough to speak the language. Use AI to kill the busywork – then spend that time on what actually matters: people.
We need more PMs like you, not fewer.
