3.3 Impossible states
Similarly, impossible substrates, or impossible states of substrates, are those that are forbidden by laws of nature. The task of transforming a possible state into an impossible one is of course impossible, but impossible states may nevertheless appear in the formalism of subsidiary theories, and transforming one impossible state into another may well be a possible task. For example, Maxwell’s electrodynamics denies the existence of magnetic monopoles, but also predicts how, if they existed, they would interact with electromagnetic fields. This allows the construction of monopole-detecting instruments, which are constructors capable of testing the prediction that no monopoles exist. 3
Those two underlined parts are the key to understanding this. In the example I linked to, blues licks, the general evolution of states proceeds by applying possible transition tasks that result in a new state that is not impossible. More specifically, two existing licks might produce an offspring which is a piece of the beginning of one lick and the ending of another lick. This offspring will be viable if it fits the requirements of what is possible. If not, that offspring might be tossed in the bit bucket, or it might be placed in a special domain for impossible states. Then, at a later time, that offspring may be mated with another lick and create a new viable offspring that that is a possible state. In that way, an impossible state is transformed into, or helps in the transformation of, another possible state.
You appear to have garbled what Deutsch said.
Well when you actually figure out if I have or haven't be sure to let me know.
I'll give you a clue. Where did he say it was possible for impossible states to create possible ones? Because that's what you have suggested.
Plus, you have ignored his example in favour of something else.
