"I identify with the weak person; this is one reason why my fictional protagonists are essentially antiheroes."
- Philip K. Dick

| A computer that is made of organic (biological) components, rather than inorganic materials like silicon. |
There are a number of limits that are gradually being approached in fabricating computer chips with silicon and other elements. One is size; we are coming to the point where it is no longer possible to squeeze more transistors into a smaller area. Another is power (and heat); faster processors use a lot more energy, and for that reason have a significant problem with waste heat (leave your laptop on your lap for more than 15 minutes and you'll see what I mean!).
So, why not turn to nature for a better computing model?
| Why limit oneself to silicon and protein and biochips a hundreth of a millimeter wide, when in almost every living cell there was already a functioning computer with a huge memory? A mammallian cell had a DNA complement of several million base pairs, each acting as a piece of information. What was reproduction, after all, but a compterized biological process of enormous complexity and reliability? The earliest biologic strings had been inserted into E. coli bacteria as circular plasmids. The E. coli had absorbed the plasmids and incorporated them into their original DNA. The bacteria had then duplicated and released the plasmids, passing on the biologic to other cells... the cells developed their own memory and the ability to process and act upon environmental information. |

Work has been done to create computer circuits with organic components; see this news article on the
leechulator, a calculator made up
of neurons taken from leeches.
Take a look at the entry for intellectual cell from the same book; there is an interesting quote (with a link) from a talk by Seymour Cray, the father of supercomputing, about biological computers.

'I made disks of my own voice to the number of five hundred very carefully chosen words.'
'His sensors out and working, and the whirring of the tape that sucked up sight and sound and shape and smell and form...'
'It sounds to me as though you had invented a kind of metal earthworm.'
'I don't have to tell you about the seven two-mile-diameter orbital mirrors that circulate around the satellite, making it habitable.'
'The steel tortoise gave MacKinnon a feeling of Crusoe- like independence.'
'...then back to their work, though little enough it was on these automatic cultivators.'
