Honing in on what is meant by "non-trivial" is a good point, because it will really mean different things when talking about different audiences. I took a few undergrad CS courses during some downtime recently and found them blindingly, disappointingly easy to the point where I found myself fading the (prestigious) school that created the material. They felt completely trivial, as did the assignments. On the other hand, I'd be willing to entertain the argument that I've not yet written a non-trivial program in my ~10 years working.
