The new roles are bottlenecks with job titles.

These roles aren’t emerging because the technical work got harder. They’re emerging because AI collapsed the cost of the technical work, and when the doing gets cheap, the scarce value moves to the boundary-crossing.

Every one of these titles is the market pricing a specific bottleneck cell. The technical skill is table stakes; the bottleneck it removes is the job. That’s a testable claim, and it runs both directions. It explains the roles that have already crystallized, since every one maps to a hot and persistent cell, and it predicts where the next ones appear: wherever a bottleneck cell is both expensive and durable, a role will form to remove it.

The frontier: the roles the taxonomy says are coming

The executive cells, meaning how a specific executive decides and getting the model across the line to them, are the obvious next frontier. The “AI translator to the C-suite” doesn’t have a clean title yet, but the taxonomy says it’s coming, because the cell is both expensive and durable. When a bottleneck is priced but unnamed, a role is forming to remove it.
