I read somewhere stuff like Second Life, Google Earth etc were directly inspired by Snow Crash.
There's some other themes in Snow Crash we are just starting to see as well:
-Government difficulties with taxation of digital goods and currency
-Companies competing to attract drivers/messengers etc (basically the uber/gig ecconomy)
-For profit surveillance and commercialization of intelligence data
Cryptonomicon covers this, too. Arguably so does REAMDE.
From Veblen's Theory of the Leisure Class (1899):
...the cheap, and therefore indecorous, articles of daily consumption in modern industrial communities are commonly machine products; and the generic feature of the physiognomy of machine-made goods as compared with the hand-wrought article is their greater perfection in workmanship and greater accuracy in the detail execution of the design. Hence it comes about that the visible imperfections of the hand-wrought goods, being honorific, are accounted marks of superiority in point of beauty, or serviceability, or both. Hence has arisen that exaltation of the defective, of which John Ruskin and William Morris were such eager spokesmen in their time; and on this ground their propaganda of crudity and wasted effort has been taken up and carried forward since their time. And hence also the propaganda for a return to handicraft and household industry. So much of the work and speculations of this group of men as fairly comes under the characterisation here given would have been impossible at a time when the visibly more perfect goods were not the cheaper. - p162
