My question goes to the rise of autonomy, semiosis, information [Shannon, successful communication] and awareness. What are the guides to the system?

I would suggest you rephrase your question in light of Szostak's work.

Go through the video, visit his site, read his published writings, and come back with some detailed statement of where he is wrong.

I just read Szostak's bio at HHMI and was not impressed enough to want to go further. It said:

Today, Szostak's main focus is the construction of a simple, artificial cell that can grow and divide as well as evolve in a Darwinian sense to adapt to its changing environment. To do this, he is attempting to make and then combine two self-replicating systems: a nucleic acid (such as RNA or DNA) that can transmit genetic information and a simple membrane-bound vesicle that keeps the nucleic acid chains from drifting apart. A major challenge is coordinating the growth and division of the membrane-bound vesicle with the replication of its contents. Szostak has found that the nucleic acids themselves can drive the growth of the fatty acid membrane; as they replicate, the internal osmotic pressure increases, swelling the vesicle and stretching the membrane so that it absorbs fatty acids from other vesicles that are under less internal pressure. Cells with faster nucleic acid replication should therefore grow faster than cells with slower nucleic acid replication. In this way, simple physical principles coordinate the replication of the nucleic acid genome and the replication of the rest of the cell structure, leading to the emergence of natural selection and Darwinian evolution based on competition between cells.

This is merely an extension of Wimmer's experiment. According to this bio, he, like Wimmer, is starting with the message and presupposing autonomy, semiosis, awareness and information [Shannon.]

Again, my question goes to the rise of autonomy, semiosis, information [Shannon, successful communication] and awareness. Not taking it as a "given."

Since you are obviously aware of his work, perhaps you can tell me whether he addresses those specific points on the order of the mathematicians and physicists who have. (e.g. Pattee, Rocha, Yockey)
