> philosophizing about whether a Turing machine can simulate a human brain
Existence proof:
* DNA transcription (a Turing machine, as per (Turing 1936) )
* Leads to Alan Turing by means of morphogenisis (Turing 1952)
* Alan Turing has a brain that writes the two papers
* Thus proving he is at least a turing machine (by writing Turing 1936)
* And capable of simulating chemical processes (by writing Turing 1952)
