> This shows how immature the field of software engineering is. Imagine bridges or houses were built like that. Or your surgeon was trained like that.

It's not that software engineering is immature, it's just more dynamic.

We are not the surgeon, we write the surgeon. We write a surgeon to fix a broken leg. Once that is done, we don't have to fix another leg. Now we need to reattach a finger. Once that is solved, maybe replace a kidney.

You cannot repetitively train or have strict rules for that, because every time it's something new. You need to have broad knowledge and experience to be able to fight the next unknown challenge. It's unknown because it's never been done before, or it has been done but your competitor will not reveal the details.

Building bridges or being a surgeon sounds very boring to me, since it's always the same (maybe some minor variants). Building software? Very much not the same.
