Technically where could be two types of successors:
1) More complex and interesting, like post-humans and some types of strong AIs
2) Boring, and just enough complex to kill us. Examples are Grey goo, paperclip maximizers, or SETI-attack AI.
The first type may be still non-friendly and dangerous, like Homo sapiens were for Neanderthals, but it will continue evolution of intelligence on Earth. The second type is the End.
