Apprenticeship is how software used to survive. Not scale. Survive.
A junior sat next to a senior. They watched mistakes get made in real time. Bad abstractions. Leaky assumptions. A test that passed but shouldn’t have. You learned why something felt wrong before you learned how to fix it. The feedback loop was measured in weeks, sometimes months. Slow. Human. Expensive. Necessary.
We are short circuiting that path.
The Seat That Got Replaced
AI now sits where the senior used to sit. It answers instantly. It patches over confusion. It fills the gaps before the junior even knows there was a gap. The code runs. The PR passes. Nothing hurts. Nothing sticks.
And we tell ourselves this is efficiency.
The senior used to say “stop” before you committed something that technically worked but structurally decayed. The senior knew the codebase had scar tissue. Knew which module was rebuilt twice because someone optimized for the wrong metric. Knew the config file that looked dead but kept a payments integration alive. That knowledge lived in a person, not a wiki. It transferred through proximity. Through friction.
AI does not teach you when to stop. It teaches you that stopping is unnecessary.
The model does not pause to explain why your solution is brittle. It does not tell you the last three developers who tried that approach left the company. It does not push back. It completes. That is what it was built to do.
The Cliff We Built
Juniors are no longer allowed to be juniors. We hand them the full stack on day one. Cloud. Infra. Frontend frameworks. Build pipelines. Observability. Security. All of it. The surface area of a modern application would have taken a team of ten a decade ago. Now we expect one person to hold it, with AI filling every crack they cannot reach.
Then we act surprised when they reach for it as a crutch instead of a reference.
We built the cliff and mocked them for grabbing a rope.
A junior shipping production code with heavy AI assistance looks identical to a mid-level engineer on a dashboard. Same velocity. Same PR count. Same deploy frequency. The difference only surfaces during an incident, a design review, or a migration. By then the gap is load bearing.
This is not AI weeding out ineffective developers. It is burning the roots.
Where Judgment Forms
Apprenticeship is where judgment forms. Where taste develops. Where you learn when not to ship, not just how. The painful lessons carry the most weight precisely because they cost something. A wasted sprint. A rollback at 2am. A feature that passed every test and broke every user expectation. Those scars are the curriculum.
If that layer collapses, the trunk still stands for a while. Seniors carry the load. Experience papers over the cracks. Attrition starts quietly. Someone retires. Someone burns out. Someone leaves for a role that still values what they know.
Then one day there is no one left who remembers why the system looks the way it does.
No room to regrow.
Who is training the person who will maintain this system in five years?// The uncomfortable question
I worry not for job security. I worry for security itself. The kind that comes from a team where at least one person has been wrong enough, long enough, to know what right feels like without being told.
That person was made slowly. There is no shortcut that preserves what the slowness produced.
