That's kind of how I think about bootcamps pumping out web devs. They're like trade schools, teaching you just enough fundamentals to know how to use existing tools.
Mostly agree... though I don't think the bootcamps get enough fundamentals in. Not to mention that it takes the type of person that will go above and beyond what has been assigned to succeed trying to be a productive employee in the space. I'm self-taught and the first years of my career spent countless hours reading, practicing and solving problems. I still spend a good 10-15 hours a week reading and exploring software development and try to at least keep up with what's out there. In the end, the best you can do is be aware of what, or even that options are out there.
