Right. I've worked with many machines that can chop or rip off limbs and I can't think of a single instance in which the operator even had access to the manual. "Push these two buttons and this foot pedal to make it go. Don't wear loose clothing." If it was more complicated than a few button-presses to use and that risky, it would either be operated by a team or it wouldn't be used.
The only single-operator machine I can think of which has an interface even 1/10th as complex as git is an automobile. The number of fatal accidents that could be remedied by reading the manual is vanishingly small.
It is not a different league it is a different sport. If a factory was designed with the equivalent of gits usabilty today, it wouldn't even get a permission to be built based on the plans alone. Also the person who planned it would have a hard time ever doing so again.
If git was a bridge it would have no handrails and it would oscillate in certain winds and for some odd reason there is a roundabout in the middle.
It is still better than no bridge for sure. As one of the first of its kind a lot can be excused, but fundamentally better engineering is possible as well.
