As a junior, this scares me. I don't think I'll be out of a job soon, but certainly the job market will change drastically and the times where SWEs are paid like doctors and lawyers will end?
Make sure you learn a lot. Ask the LLMs to explain anything you don't deeply understand. With all of these coding assistants, there will be many juniors that get a lot done, but don't really understand what they are doing, and their worth will drop quickly. So far LLMs are great at producing code, but not at architecture or maintenance.
I'm just restating the obvious because LLMs can do exercise for you, but there is not much to be gained if one follows this path.
