Finally, we might decide that civilisation itself is worth preserving. In that case we have to work out what to save and which people would be needed in a drastically reduced population - weighing the value of scientists and musicians against that of politicians, for example...

'Temes' [technology-enhanced memes] don't care about us - they simply want to create more of themselves. Don't think we created the internet for our own benefit - think about temes spreading for themselves because they must.

Parapsychology seems to be growing further away from the progress and excitement of the rest of consciousness studies.

One of the biggest mistakes that people make when they think about memes is they try to extend on the analogy with genes. That's not how it works. It works by realizing the concept of a replicator.

All other species on this planet are gene machines only. They don't imitate at all well; we alone are gene machines and meme machines as well.

In proportion to our body mass, our brain is three times as large as that of our nearest relatives. This huge organ is dangerous and painful to give birth to, expensive to build and, in a resting human, uses about 20 per cent of the body's energy even though it is just 2 per cent of the body's weight. There must be some reason for all this evolutionary expense.
