It's a theoretical risk; you mitigate it by just having smart people that have a good analytical mindset that can learn. As it turns out, the most important thing you learn in university is the ability to acquire new skills; not any particular skills. That ability is not unique to computer science. Another thing is that languages and tools that require a lot of formal background are a hard sell in industry because it means having to hire more scarce and expensive people. It's a reason that functional programming was a hard sell for a long time until languages got good enough that normal people could figure it out. Scala was an early example that did not quite get that right maybe. Too difficult for people without a CS degree and a good understanding of type systems. Indeed the whole language became a bit of a playground for type system nerds. It got a bad reputation for being hard and a bit over engineered. Javascript and python, both of which now have some level of functional programming support, are much easier to pick up by other people. Which is why those languages are so popular. Any high school kid can work with this. I currently have a couple of summer interns in my team. These two languages are what they know.
