AI has torched the market for junior programmers

Stanford's Digital Economy Lab pulled ADP payroll data and found something brutal hiding inside otherwise healthy tech employment numbers. Software developers aged 22 to 25 are down 19% since late 2022, while every cohort over 30 grew, with 41-to-49-year-olds up 14%. Total developer headcount is actually up 4.4% over that same stretch, which is exactly why studies that only look at averages keep missing the story. Juniors are just 8% of the workforce, so their collapse barely dents the aggregate, even as it guts an entire generation's on-ramp into the field.

The timing points at agentic coding tools, not ChatGPT itself. The junior employment line peaks a couple months before ChatGPT even launches, drifts down through 2023, then falls off hardest in 2024 and 2025 -- right when coding assistants stopped autocompleting lines and started finishing entire tickets. BLS data backs this up at the job-title level: "computer programmer" roles, the ones defined by writing code to someone else's spec, fell 16% in a year against a projected 6% decline per decade. Web developer and QA testing roles fell too. Meanwhile data scientist roles grew 12% and systems analyst roles grew 4.4%, because those jobs are about judgment rather than typing code to order.

Here's the twist: a huge wave of new builders did show up, just not under the job title "programmer." GitHub added 36 million new accounts in its fastest growth year ever, and 80% of them used Copilot within a week. App Store submissions, which require a $99 fee and an actual working binary, grew 24% in 2025 after eight straight years of decline, and jumped 80% year-over-year in early 2026. Vercel says 63% of its vibe-coding users aren't developers by trade; Lovable puts that figure at 60%. Marketers, teachers, and product managers are shipping real software, but in labor statistics they still count as marketers and teachers.

The uncomfortable part is what breaks next. The old system trained senior engineers by having them review junior engineers' mediocre code for years. AI now writes that mediocre code, so nobody's hiring the junior, so nobody's in line to become the reviewer. Meanwhile the code being shipped by all these newly-minted builders isn't getting reviewed by anyone: a Veracode study found 45% of AI-generated code fails basic security tests, and Apple's app review queue has stretched from two days to weeks under the submission surge. IBM is tripling entry-level hiring and redesigning junior roles around specification and customer contact; Salesforce, by contrast, hired zero engineers last fiscal year. Which of those becomes the norm will decide whether the industry has senior engineers a decade from now.

Indeed's postings data has ticked up for thirteen straight months since bottoming in May 2025, which is the first hint of a possible correction. But hints aren't a ladder. Programming didn't die here -- it turned into a capability like typing did, useful to nearly everyone and owned by no one job title. The people who lost out are the ones who were about to start climbing the career ladder just as it got kicked away.
