The thing people miss in these “replace juniors with AI” takes is that juniors were never mainly about cheap hands on keyboards. They’re the only people in the org who are still allowed to ask “dumb” questions without losing face, and those questions are often the only signal you get that your abstractions are nonsense.
What AI does is remove a bunch of the humiliating, boring parts of being junior: hunting for the right API by cargo-culting Stack Overflow, grinding through boilerplate, getting stuck for hours on a missing import. If a half-decent model can collapse that search space for them, you get to spend more of their ramp time on “here’s how our system actually fits together” instead of “here’s how for-loops work in our house style”.
If you take that setup and then decide “cool, now we don’t need juniors at all”, you’re basically saying you want a company with no memory and no farm system – just an ever-shrinking ring of seniors arguing about strategy while no one actually grows into them.

Always love to include a good AI x work thread in my https://hackernewsai.com/ newsletter.
