I am being serious...

the damage certain software engineers could do certainly surpasses most doctors

Ah sorry, I misread it as coming from someone who doesn't want licensing, so you were appealing to HN by switching to software engineers (and I know many on here loathe to think anything beyond "move fast and break things", which is the opposite of most (non-software) engineers.

But yeah, I'd be down for at least some code of ethics, so we could have "do no harm" instead of "experiment on the mental states of children/adolescents/adults via algorithms and then do whatever is most addictive"
