"intern or college-hire"

It's well known that these fresh employees are not going to contribute to velocity of a team for at least a year. They're investments. I've seen levelling docs specifically call this out.

"It's prone to spiraling off into the weeds, makes silly mistakes, occasionally mangles whole repos (commit early, and often), and needs very crisp instruction and guidance"

This describes a team of juniors. If it's describing an entire team, then everyone above mid-level needs to be fired.

I will say that I think "the bottom of the market getting eviscerated" is going to apply to software devs too. There is now very little point in hiring someone who already only produces slop as their best output. The main people who need to be afraid of AI in the next 5 years is probably offshore and near-shore people, and perma-juniors who have done the "1 year of experience 10 times" thing.

We hire folks who make slop so we can form them into folks who turn that energy into elevated output. However, I expect that the junior engineer crop will teach us a thing or two about assisting coding techniques, and we'll owe it to them to level up their system design and abstraction skills.
