"For the next few years, I concentrated on getting rid of as many employees as I could, by replacing them with automatic machines. I'd design the control circuits myself, in many cases wire the things up myself, always concentrating on replacing men with machines. But it wasn't very successful. I found that the more automatic I made my plant, the lower my costs went. The lower my costs went, the more business I got, and the more I had to expand." Lexington scowled. "I got sick of it. I decided to try developing one multi-purpose control circuit that would control everything, from ordering the raw materials to shipping the finished goods. As I told you, I had taken quite an interest in biology when I was in school, and from studies of nerve tissue in particular, plus my electrical knowledge, I had a few ideas on how to do it. It took me three years, but I began to see that I could develop circuitry that could remember, compare, detect similarities, and so on. Not the way they do it today, of course. To do what I wanted to do with these big clumsy magnetic drums, tapes, and what-not, you'd need a building the size of Mount Everest. But I found that I could let organic chemistry do most of the work for me. "By creating the proper compounds, with their molecules arranged in predetermined matrixes, I found I could duplicate electrical circuitry in units so tiny that my biggest problem was getting into and out of the logic units with conventional wiring. I finally beat that the same way they solved the problem of translating a picture on a screen into electrical signals, developed equipment to scan the units cyclically, and once I'd done that, the battle was over. "I built this building and incorporated it as a separate company, to compete with my first outfit. In the beginning, I had it rigged up to do only the manual work that you saw being done a few minutes ago in the back of this place. I figured that the best thing for me to do would be to turn the job of selling my stuff over to jobbers, leaving me free to do nothing except receive orders, punch the catalogue numbers into the control console, do the billing, and collect the money." "What happened to your original company?" Peter asked. * * * * * Lexington smiled. "Well, automated as it was, it couldn't compete with this plant. It gave me great pleasure, three years after this one started working, to see my old company go belly up. This company bought the old firm's equipment for next to nothing and I wound up with all my assets, but only one employee--me.
