This just isn't how software is built in practice. Engineers make dozens of architectural decisions every day. They may feel like small ones, but over time they add up to a whole lot of surface area. The skills you learn in Computer Science provide a whole lot more context for your decision making when actually building things. Bootcamps, at least from the folks I've interviewed so far, simply don't prepare their graduates to do real work. This is particularly true when it comes to data structures and basic algorithms. Two really key fundamental knowledge areas if you're goal is to build actually reliable and relatively efficient software.
This isn't to say that all CompSci graduates are good programmers (clearly they are not). It also isn't to say that everyone coming out of a bootcamp is bad (they are not, I recently hired my first). But when painting with a broad brush bootcamp's right now seem to mostly churn out students who are sort of comfortable with syntax and very basic logic, but not much else.
I'd be interested to see this article go farther. What do these cohorts look like in two years? Does that fundamental knowledge gap hold those bootcamp graduates back? I suspect it does, but I have very little proof but my own intuition. I'd love to be wrong.
