In spite of the solid alliteration, "Vacuum Valve Valley" was never likely to quicken the pulse of the 1940s venture capitalist. And although it seems that the micro-electronics of the 1990s were based on gallium arsenide chips, a Gallium Arsenide Grid - or Gulch - sounds unhealthy. So we are left with the Silicon Valley phenomenon, full of young people, many unmarried. As the authors of "Silicon Valley Fever" point out, Silicon Valley is not interested in Culture with a capital "C" - art, music, opera or literature. These are not areas of human endeavour in which the Valley can be expected to innovate.
As something of a scientist, Sydney Grew, I feel obliged to defend the culture of Vacuum Valve Valley, Silicon Valley and any other valley you care to mention.
The point about technology, I guess, is that it is not culture per se, yet it enables new forms of culture to develop. For example, Hollywood is the spiritual home of cinema, arguably the greatest artform of the twentieth century, which developed out of advances in photography during the nineteenth century.
As for science and technology, whether in Vacuum Valve Valley, or anywhere else, new technologies allow us to express ourselves in entirely new ways. Radio, television and the internet, for example, allow the creation of completely new forms of communication and human expression, including entirely new artforms. So the culture of Vacuum Valve Valley may belong to the future, and not to the past.
