Machine doesn't get mad when an app takes forever to start or keeps constantly crashing, but we humans do. Writing "clean" code has the least importance when it comes to machine generated code.
This is so far from the truth that I really think anybody who still says this has not actually used it for anything real in at least a couple years.
Yes, I'm not saying it will always generate you the best code, sometimes it may even be bad.
What I am saying is it CAN generate code that is reasonably performant, sometimes even more performant than you would have written it given time constraints, and fulfills requirements (even if sometimes it requires a little bit of manual effort) much faster than we ever could before.
But if your assertion is that using AI for code generation and being successful with it makes you a junior engineer, then good luck keeping your job in the future. Just take a look at social media and there are a plethora of examples of prominent engineers using it with success.
