No, generics are by no means obsolete. The were also introduced into
Modula-3, which already had inheritance, by people who like simple
languages.
You can simulate generics with inheritance (the technique is described
in Meyer's "Object Oriented Software Construction" (very good book
BTW)), but it is really just a simulation, not the real thing. You loose
type checking among other things. Note that Eiffel also has generics.
