Python has been a common teaching language for at least a decade now, it's just that this particular course has now switched to it as well. Still took 15 years for it to get that momentum, though.

You won't see a CS course taught in Go or Rust anytime soon.

There actually have been a few CS courses taught in Rust. http://rust-class.org/ was a few years back, but http://cis198-2016s.github.io/ is being taught at Penn and http://homepage.cs.uiowa.edu/~achampion/teaching/plc/lecture... is being taught at the University of Iowa _right now_.
