From Self-Organizing Systems-1962 [link]Paper  abstract   bibtex   
CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): In the second part of this talk I will speak about evolution. In the first part I will present a conjecture which states that there is a maximum rate at which data processing can proceed. This maximum rate applies to all data processing systems, manmade as well as biological. Practical computers do not reach this rate, which, however, seems to constitute an ultimate physical limitation on the progress of computer design. Biological systems are subjected to the same limitation. Hence we get an upper bound on the amount of data processing that is going on in nature and on the amount of bits that have been processed since the beginning of life on earth. I hope that this conjecture may stimulate the discussion towards a tightening of concepts in artificial data processing and biological evolution alike. The conjecture is the following: No data processing system whether artificial or living can process more than (2 ×1047) bits per second per gram of its mass. This figure refers to a self-contained system where the power supply is included in the total mass. "Processing of n bits " is defined as the transmission of that many bits over one or several channels within the computing system.
