SDR/BDR is the obvious answer but I'd push back on the framing a little. The role isn't the variable - the operating mode is. Any GTM role built around execution (outbound volume, task completion, process adherence) is at risk.
Any role built around judgment (synthesizing context, challenging assumptions, guiding decisions) survives. AI isn't killing the SDR - it's killing the execution-first version of every role on this list, including AE.
I've been writing about this specific shift for a while. Just finished a book on it if anyone wants an early read.
