I can only repeat what I said on one of the many previous occasions this has been mentioned:

Dreadful - absolutely dreadful. It starts so well, then just turns into a thinly veiled rant/diatribe/spiel about an overly optimistic forecast of what the future could, but won't, be like.

Bad writing, bad philosophy, bad predictions. Just awful.
