Actually, JPod, if my techno-geek friends are right, a hundred years from now we shall have passed through the Singularity and the worst political sin you can be guilty of will be “substratism”–e.g. irrationally preferring entities like us, with minds arising from a biological substrate, to the highly intelligent (and, let’s hope, amiable) descendants of today’s computers, with their silicon substrates.

On the other hand, if the techno-geeks of my childhood had been right, I would already have a flying car, and a weekend home in the Asteroid Belt too.
