Now he would have genetic proof, you might think: our DNA is more "virus" than "human". -- Well, the old retroviruses are almost all defective so they don't matter much. Also, noncoding but function-holding RNA and regulatory sequences - ''tools'' and ''building instructions'' - have been identified from the junk now. So, yes, no need to panic, we are still human enough. | ||

That's the point which is especially interesting, because of the analogy to biological ''components''. Also, biological brains use one type of ''component'' for two things - the neurons store '''and''' process information. | That's the point which is especially interesting, because of the analogy to biological ''components''.
