More and more detail. :-)
Ackermann goo, or Ice-nine, a glimpse of it. In the last post [1] I describe a scenario where small Ackermann molecules made with RNA (see the announcement [2]) may lead to a grey goo situation.

Grey goo [3] is a hypothetical result of uncontrolled replication of nanodevices. In real world it would be limited by the resources available. After all what stops a bacteria to replicate forever, until it uses all Earth resources? Well, the availability of them.

In this Ackermann goo scenario, if we use a molecule for Ackermann(4,4), say, then the number of the atoms would be larger than the whole number of atoms in the universe. However, there is an availability problem: all rewrites are done by rewrite enzymes, so in reality a solution which contains some ackermann molecules and enzymes will turn into a (grey? what color?) goo, then stops because there are no more available enzymes capable to achieve the key positions for new rewrites.

But just imagine that the enzymes are not some weird artificial ones, but real ones from almost any living cell. Then, if you stick your finger into the goo... Ice-nine! Only not with water. What's Ice-nine? [4]

This scenario is faulty though. Because if real enzymes are involved as rewriting enzymes of RNA, then the same might happen all the time, everywhere, because they are all abundant in the living realm. So why it does not happen? Sometimes it does, most of the time it doesn't, it's resource availability, as usual.

[2] Announcement: there exists an encoding of chemlambda molecules with RNA, in such a way that the chemlambda model can be realized via real RNA computing
