Will AI Replace Junior Software Developers?

Moderate Risk60%

Editorial estimate, synthesized from CEO statements, AI-attributed layoffs, and automation research, the same method as the Calculator. A provocation, not career advice.

AI writes a huge share of the code now, and the entry-level rung where you used to learn the craft is the part getting kicked out.

The Factors

Pushes it up

Google says 75% of its code is AI-generated. Microsoft says 20-30%. A Stanford study found employment for developers aged 22-25 fell nearly 20% from 2022 to 2025. Big firms are pulling back on new-grad hiring while posting for senior roles.

Pulls it down

Someone has to architect, review, debug, and own the system. Senior engineers who can wield AI are in demand. The danger isn't 'no developers.' It's 'no on-ramp to become one.'

The Receipt

75% of the company's code is now AI-generated.

Sundar Pichai, CEO, Google (2025).

Pichai's 2025 figure was a massive jump from the 25% he cited at Google's late-2024 earnings call. A Stanford study tied the rise of AI coding tools to a ~20% employment drop for developers aged 22-25 between 2022 and 2025.

What the Machine Still Can't Do

AI can generate a function. It can't decide what to build, own the architecture, or take responsibility when the system fails at 3 a.m.

What to Do About It

Even AWS's own CEO called replacing juniors with AI 'the dumbest thing.' When companies kill the entry rung anyway, that's a choice. Document it in the Layoff Index. A risk score is a reason to organize, not to despair.
