this one, claiming something about how Shannon's limit of computations
might be reached already in biological human brains and that via some
"timing coding", which should be impossible to imitate even with digital computers
.. he is beyond boring.

In the entire human genome there are only 3 billion base pairs. There are 4 bases so each base can represent 2 bits, there are 8 bits per byte so that comes out to 750 meg. Just 750 meg! And all that 750 meg certainly can be used just for the master learning software algorithm, you've got to leave room for instructions on how to build a human body as well as the brain hardware. So the instructions MUST contain wiring instructions such as "wire a neuron up this way and then repeat that procedure exactly the same way 917 billion times". And the 750 meg isn't even efficiently coded, there is a ridiculous amount of redundancy in the human genome. So there is no way, absolutely no way, the algorithm can be very complex, and if Evolution could find it then it's just a matter of time before we do too. </font></div><div class="gmail_default"><font size="4"><br></font></div><div class="gmail_default"><font size="4"> John K Clark</font></div><div class="gmail_default"><span style="font-size:12.8px"><br></span></div><div class="gmail_default"><span style="font-size:12.8px"><br></span></div><div class="gmail_default"><br></div></div><div class="gmail_extra"><br></div><div class="gmail_extra"><br></div><div class="gmail_extra"><br><div class="gmail_quote"><br></div><div class="gmail_quote"><br><div><br></div></div></div></div>
