MPI professor: I can advise 6 PhDs but only 2-4 AI agent projects at once

Michael Black (Max Planck Institute) shares part 3 of his "PhD Advising vs Vibe Coding" series. He can comfortably supervise 6 PhD students and manage 8 while working hard, but struggles to advise 6 AI projects at once.

The reason is cadence: AI agents work fast and return with answers or questions needing his analysis multiple times a day. Meeting each agent weekly like a PhD student would defeat the efficiency gains. His conclusion: 2-4 concurrent AI projects is the sweet spot given his other responsibilities.
