well if driving is supposedly safer when automated, why not code

The qualities of computation that make autopilots safer than human drivers aren’t the same qualities that produce better designed software products.

to err is human

It’s supposedly safer than the average driver, not safer than professional drivers.

the average american spends 60 minutes a day driving, that's thousands of hours by the time you reach 25... at what point is that not a professional level of experience?

Is it actually safer? If you can't understand the code you can't verify it's safety, and AI code often has bugs in it. You can't trust implicitly.

You don't need to understand code to verify its safety if you have a good QA framework.

Same applies to driving cars
