Topic Suggestion for a Computer Science presentation

Question

As a part of my undergraduate studies I have to do a presentation of 20 mins on any interesting and latest computer science topic in front of a technical audience. On searching for the same I found the following topics interesting

Swarm Intelligence, Semantic Web, Ant Colony Optimization Algorithm

Any suggestions of topics or references to add for the above would be much appreciated.

Answer 1

I'd want to hear more about programming collective intelligence and creative use of statistics (e.g., Peter Norvig's spell checker).
