Not mentioned in the video are a couple factors that probably influence the process in invisible and important ways:
1) At UH (and other universities I've checked on), the different departments are run as different business units, so trying to run mixed classes runs into the typical corporate politics of how funds are allocated, who gets credit, etc. We do have a video game design class that combines CS and creative media majors into one crossover class at the undergrad level, so I'm trying to gain insight on how that works at a pedagogical and administrative level.
2) Talking to the curriculum manager of our MBA program, he expressed that he didn't have any professors who would want to teach a multidisciplinary class, and he didn't have anyone he felt comfortable assigning to it anyway. When I asked him why, he said that business academia heavily discouraged multidisciplinary research, and publish-or-die culture has resulted in extremely "pointy" professors who are stellar single business discipline, but essentially worthless outside their skill silo. Because of this, he felt that a silo-breaker class would be either resource-intensive or ineffective.
We do have a couple "entrepreneurship" centers on campus, one oriented around tech (with a former technical SV-type manager), and one oriented around business. Sadly, they seem to be mutually exclusive for the most part, but I've been working on trying to build the connective tissue.
I do completely agree that business and engineering need each other, because I always see product without strategy or strategy that completely misunderstands the magical business properties of pure tech--and that's if the business kids are pitching tech at all. These two disciplines, at least at my school, are utterly ignorant of each other and it shows in the ideas they have. When it comes to preparing students for any kind of entrepreneurship, you need to have practitioners and managers mingling for it to work, and I doubt I'd ever go to a business masters that wasn't multidisciplinary. To this end, very happy I'm seeing things like Harvard's MBA/CS and the Stanford interdisciplinary programs pop up.
I doubt I'll get UH to see the light, but wish me luck. Hopefully the insights I got from administrators help someone look at the problem differently.
