Thanks Pat, for bringing us all back into the real world

But to end (?) this topic in a more positive way:

What is great about Generics?

1) I like them a lot, type erasure or not

But most of all:

2) they sometimes give rise to very interesting and entertaining topics!

My answer:
1. People expect too much of it.
2. The compiler warnings are crap.

If you actually read Gilad Bracha's paper (now, thankfully, translated to the tutorials), he explains the issues with implementation, which basically boils down to the fact that, for whatever reasons, Java was NOT able to make typed classes first-class objects, so they chose the next best option that was backwards bytecode-compatible: type erasure.
