Can also confirm. Almost any output from claude code needs my careful input for corrections, which you could only spot and provide if you have experience. There is no way a junior is able to command these tools because the main competency to use them correctly is your ability to guide and teach others in software development, which by definition is only possible if you have senior experience in this field. The sycophancy provided by these models will outright damage the skill progression for juniors, but on the other hand there is no way to not use them. So we are in a state where the future seems really uncertain for most of us.
