> There is a material difference between the signal from an internship (~7 weeks of usable work time after ramp-up) vs a co-op (5 months actually working)

And that's why the trades require you to perform years of work as an apprentice before you're ever qualified to pass an exam to become a journeyman. Not only is it like a years long internship, but you're paired with someone who has already passed a high bar. You're learning directly from vetted people, and those people can vouch for you.

> University of Waterloo famously sends their Computer Science students through a total of six internships, giving them roughly 2 years of real-world work experience before they graduate.

Still less time than an apprentice is required to work, but it's better than nothing. Most trades require you to be an apprentice for 4 to 5 years.

> The reason is, hiring engineers has historically been so competitive that you couldn’t convince a senior engineer to do an internship [...] So the industry converged on not requiring it.

Which is one reason the trades made it the law that you have to follow the apprenticeship in order to become a journeyman. "The contracting companies don't feel like hiring licensed workers" isn't an option. Companies don't do the right thing unless they're forced to.

This is why we need professional engineer certification for software engineers. We need a rigorous, time-tested, reliable process to ensure engineers have actually done the job in the right way. Otherwise it's a bad guessing game like Steve is explaining.

This is also why we need a software building code. We need to explicitly define exactly how you're supposed to engineer, so that we can create a certification that people can pass. Otherwise designing and building software is completely subjective. Engineering should not be subjective.

This is not some mysterious experimental idea that nobody knows if it'll work. Trades have been doing this for decades. It's not perfect, but it's much better than the alternative.
