Former healthcare to software engineer working on a master's here. My colleagues who were licensed back in healthcare weren't all of the same quality. They all made mistakes at one point or another, some pretty bad some minor. There's no difference though, minor could just as well become major.

The way they get around it in healthcare is by throwing more people at the problem. You have a physician who is good at pointing in the general direction of the problem and a solution, then you have all the auxiliary staff who will narrow down on the solution based on their field. But at any single point all of them could fuck up, or one of them could.

Now that I'm a software engineer and I've written enough code to do stuff. I can confidently say that licensing will not solve this problem. Especially if there aren't enough people involved. Which is probably what was missed in the beginning.

Anyway long rant over.

Never gonna happen as long as the demand is so much higher than the supply.

Perhaps it should be a requirement for certain things though, like the medical area.
