Investment shift
Headcount expense drops. Per-person investment goes up. Hiring bar goes through the roof.
The people at the core are the most expensive on the market. Top of field. They have the judgment to know when the agent is wrong and the instinct to design workflows that compound.
Pay for them. If you will not pay top-of-market for the five who replace your forty, you get agents writing code nobody can evaluate, shipping features nobody validated.
Warning
That is chaos with better tooling.
What is no longer needed
Every twenty-person team has people whose primary contribution is gathering requirements, writing test plans, updating documentation, scheduling meetings, creating status reports.
Talented people doing work that an agent does in minutes. Pretending otherwise is not kind. It is crueler.
Governance
Compliance automated in the pipeline. Security scanning on every commit. Quality gates controlled by code.
