Below where they'd be if they had kept pace with peers in non-AI-exposed fields. The gap was 15% a year ago. It is widening.

The split nobody is talking about
Stanford researchers tracked millions of U.S. workers through real-time payroll data — not surveys, not job postings, not LinkedIn profiles. Administrative payroll records. What they found underneath the calm headline number should change how you think about hiring senior technical talent.
Flat → ↑
Same AI-exposed occupations. Flat or genuinely growing. In some categories, the senior cohort is pulling ahead.
"You have two groups in the same occupations moving on opposite trajectories. And this gap is opening through hiring — not layoffs."
Companies are not firing junior people. They are simply not creating the entry-level roles that used to be there. The door is closing quietly. And the downstream effect on your senior hiring pipeline is something almost no one is discussing.
The mechanism behind it
The Stanford researchers identified exactly why this split is happening. AI is not displacing all knowledge work equally. It is displacing two distinct types of knowledge very differently.
01
Codified knowledge — being displaced
Formal, documented, standardised knowledge that can be taught, written in a textbook, or described in a procedure. Exactly the kind that justified hiring someone six months out of school.
02
Tacit knowledge — being amplified
Pattern recognition built over a decade of shipping, breaking and fixing things. Judgment under ambiguity. Knowing what failure looks like before it happens. AI does not replace this — it amplifies it.
03
Senior engineers are protected — and scarce
They are staying put longer, wielding more leverage — and they stopped applying to job posts a long time ago.
The implication for hiring: Installing an AI resume screener on top of this reality means you have just built a faster way to sort through people who were never your target candidate in the first place.
"How do I identify my next three senior hires before I actually need them?"
This is where the leverage actually sits. Not in which AI screening tool to install next.
The companies winning on senior technical talent are not those optimising job posts or installing AI screening tools. They are the ones building relationships with senior engineers before roles open — having real conversations before there is urgency on either side, and understanding what would make someone consider a move.
If your process cannot answer the question above, the solution is a system that operates continuously, builds relationships proactively, and gives you decision-making capability before urgency forces your hand.
