Is there any system where "people with industry experience come to teach [students]" actually happens? From what I've seen (in the USA and similar places) contribution of industry veterans extends mostly to guest lectures, which is a very rare happening and the purpose is motivation and recruiting rather than education. Industry and academia are universally two very distinct paths, and the split happens very early on in one's life. I personally haven't seen the former significantly contributing to the latter. The reverse, interestingly, is a lot more prevalent.
