Amino acids are put into a sequence with construction tools (transfer RNA)
outside the protein.

the instructions/design decisions about what will be build are also outside
the protein (in the DNA communicated by means of messenger RNA)

Yes, and that gives us an advantage nature did not have, reverse engineering
a brain is not easy but it's easier than making one from scratch, it won't
take us 3 billion years as it took nature.

In the flesh? What's the point?

What has that to do with flesh?

I'm far more interested in putting the information in Spikes organic brain
(or mine) into some more permanent media than I am in recreating another
meat computer exactly like the primitive thing we have now; however if you
really wanted to do it I can think of one way with minimal use of Drexlerian
technology. We would certainly know Spike's genome so we could grow a brain
from that, then just use the Drexlerian technology to modify the
interconnections in the neurons of the new brain so they have the same
memories the original brain had. As I said I very much doubt anyone will
bother to actually do something like that because they would regard it as

And you are claiming that the only way to achieve such precision is the way
nature stumbled upon 3 billion years ago and intelligence can never beat
random mutation and natural selection. That strikes me as extraordinarily

Now that I agree with.
