>>> theories do come up in any serious work Counterpoint: the overwhelming majority of software companies out there do not work on problems and develop products that warrant deep computer science expertise. I mean, if you're doing cutting edge and/or highly technical stuff, great, go nuts, recruit only those with CS degrees. But most software out there is your run-of-the-mill line of business software, mostly CRUD with a bit of specialized functionality. And the bar for working on that is way lower.
