Speed of Light

This post has nothing to do with Brunei. But it's something I thought was interesting, so never mind.

I just saw this paragraph in an article on the BBC Word Service written by Vint Cerf (here) celebrating the life and achievements of Alan Turing:

My colleagues and I have had to re-think the basic communication paradigms for large scale networking owing to the slow nature of light speed propagation (eg 20 minutes one way from Earth to Mars) and disruption caused by planetary motion.

Slow speed of light? Isn't the speed of light the fastest thing we know?

My goodness, we are living in exciting times when we are starting to worry about the slow speed of light!
