Isn't that enough for you? Do you have to call me bad names in addition?"

Naturally, there's got to be a limit for I don't expect to live forever, but I do intend to hang on as long as possible.

Now remember, kids, the internet is serious business.

Inertia! Our ruling class knows one law; no change. Despotism! They know one rule; force. Maldistribution! They know one desire; to hold what is theirs.

Modern science fiction is the only form of literature that consistently considers the nature of the changes that face us.
