I can back up without a camera, and I can "drive stick" as Americans call it. But a teenager learning to drive today should maybe not bother.
But that's not the same question as "why aren't you installing a backup camera?". Because it wouldn't change my ability or speed of backing up. And I can drive stick. Why not replace my car with an automatic? Because it wouldn't improve anything.
In fact I dislike automatics, since they'll suddenly and jerkily decide that another gear is best, ever though my foot didn't move, and inclination didn't change. But in a couple of decades it'll all be electric and this problem will go away. The deliberate engine braking is in electric cars just the brake pedal.
I still have most of the python standard library and many of the interfaces I use often in my brain, so autocomplete saves me almost no time. I can type working code into notepad about as fast as I can type it in VS code.
