One anecdote. I just use ChatGPT to help with a relatively complex project. But that depended on a number of relatively simple scripts around automating some AWS functional in Python using boto3 - the AWS SDK.

It really did help keep me in the flow. While I was designing the entire system and documenting it, I would just give ChatGPT the requirements in a few sentences and it spit out correct code.

Honestly it did take the place of what I would have formerly thrown at an intern/junior dev.

Will it “replace” the need for junior devs? I am going to say the unpopular opinion - yes.

But coding has always been the least important part of my job. Knowing what to code and solving XYProblems is where the money and differentiator are.
