I dunno, all solar systems are roughly alike. A seed does not to be
ultraintelligent, in fact it doesn't need to be intelligent at all. It
will absolutely suffice for it to generate intelligence, using local
resources. I'm not sure how small the seed can get, but given enough time
even the meekest self-replicator will do.

So you don't send it at 0.9999999 c but at 0.95 c, or something.

I don't think that's right. If you go fast enough, it only means that
you're bathing in radiation, the harder, the faster your are. This means
you have to have a metabolism, and repair the damage incrementally using
distributed encoding (within the packet, and between the packets).

Why do you expect Kurzweil to be omniscient, or only rational?

Sure they want to go compact, but this doesn't mean they're not going to
spawn off clones (which in their turn will go compact, if that's
