You can train them enough to not be helpless without a lawyer. Doctors don't need one for every medical decision they make. You do need larger support systems to make this work though and that doesn't get built overnight.

It certainly does limit new engineer throughput for society because of training times and increase salaries though.

Uh, Doctor example isn't the best seeing as there is an entire industry in existence to handle the possibility that a doctor in the course of doing their job may end up causing harm, unintentional or not. I.e. malpractice insurance.

I find this push of responsibility to the engineers encouraging. Finally may come the legislative framework through which I can shoot down an employer's design knowing that in all odds anyone else with a license at stake won't cave to mere financial coercion.

We would need a similar-in-principle industry for engineers if they are legally and professionally responsible for code. It would likely be smaller and cheaper since most of us are not responsible for lives though.

You definitely wouldn't need a lawyer on retainer.

If you work at a place like Facebook or Google it would probably be more expensive. You would be looking at liabilities in the hundreds of millions for a single bug.
