Why the "AI replaces engineers" narrative keeps failing the data test

Andrew Kew

Software engineer layoffs blamed on AI? Almost entirely theatre. A new essay from Normal Tech compiles the data — and the picture is clearer than most pundits want to admit.

"59% of U.S. hiring managers admitted they emphasise AI when explaining hiring freezes or layoffs because it plays better with stakeholders than citing financial constraints."

Block, Snap, Intuit — all recently cited AI as a reason for cuts. All turned out to have more ordinary explanations: pandemic-era hiring excess, activist investor pressure, management layer trimming. The Intuit CEO literally pushed back on the framing himself, saying the cuts "had nothing to do with AI."

What the data actually shows

  • WARN Act disclosures — New York added an AI checkbox to layoff filings in 2025. After a full year and 160+ filings, just one company checked it. Out of ~25,000 laid-off workers, 46 (0.2%) were flagged as AI-related.
  • Federal Reserve research finds software engineer employment is still growing post-ChatGPT — just ~3 percentage points per year slower than the no-AI counterfactual.
  • Layoffs are the wrong signal anyway. AI's productivity effect comes through slower hiring, not firing. Laying off experienced engineers destroys the tacit knowledge that makes AI effective in the first place.

The sandwich model

Here's the key framework. Software development has three layers:

  1. Decide — Problem framing, requirements, planning
  2. Execute — Writing and designing code
  3. Deliver — Testing, verification, integration, maintenance

AI has compressed the middle. Writing code was 9–61% of a developer's time (Microsoft research, 6,000 devs). Agents compress that dramatically.

Here's the number that makes it concrete: across 100,000 GitHub developers, AI agents produced an 8× increase in lines of code written — and only a 30% increase in releases.

The two ends of the sandwich — deciding what to build and being accountable for what ships — resist automation. Not because of capability limits, but because requirements specification and delivery accountability are structurally human-in-the-loop: user needs, business context, regulatory constraints, liability.

Why the bottleneck migrates, not disappears

As more decisions get delegated to AI, the value of human judgment moves upward. Software complexity keeps growing, so there's no ceiling. The comparison in the essay is apt: the engineer's role becomes more like a crane operator — supervising AI doing the heavy lifting, responsible for what lands where.

"Vibe coding" has muddied this picture. A solo dev shipping a toy app with LLM autopilot is very different from an engineering team accountable for production systems. The word covers both, which is why the discourse is so sloppy.

This isn't unique to software. The essay notes the same sandwich applies broadly to knowledge work — radiologists, lawyers, analysts. Software is just the furthest-along test case.

What to do

  • If you're an engineer: The execute layer is being automated. Invest in the ends — better requirements skills, stronger delivery practices, accountability at scale.
  • If you're hiring: Don't mistake AI productivity gains for headcount savings. The bottleneck moved, it didn't disappear.
  • If you're reading AI layoff headlines: Check whether the company had pandemic hiring excess, investor pressure, or consecutive net losses before crediting AI.
