The Open Thread posted at the beginning of the month has gotten really, really big, so I've gone ahead and made another one. Post your new discussions here!
This thread is for the discussion of Less Wrong topics that have not appeared in recent posts. If a discussion gets unwieldy, celebrate by turning it into a top-level post.
It seems like in gene networks, every logic gate has to evolve separately, and those restriction enzymes you mention barely do anything but destroy foreign DNA. That's less self-modification potential than the human brain.
The inability to create new logic gates is what I meant by the systems having low memory. In this case low memory to store programs.
Restriction enzymes also have a role in the insertion of plasmids into genes.
An interesting question is: If I told you about computer model of evolution with things like plasmids, controlled mutationJ_recombination); would you expect it to be potentially dangerous?
I'm asking this to try to improve our thinking about what is and isn't dangerous. To try and improve upon the kneejerk "everything we don't understand is dangerous" opinion that you have seen.
