What is the hard evidence?
Edit: What I mean by this is there may be some circumstantial evidence (less hiring for juniors, more AI companies getting VC funding). We currently have no _hard_ evidence that programming has had a substantial speed increase/deskilling from LLMs yet. Any actual __science__ on this has yet to show this. But please, if you have _hard_ evidence on this topic I would love to see it.
Closest I guess is hiring of juniors is down, but it's possibly just due to a post COVID pullback being credited to AI.
I definitely think a lot of junior tasks are being replaced with AI, and companies are deciding it's not worth filling junior roles at least temporarily as a result.
