> It appears to me that part of the reason the Silicon-Valley-Tech-VC model involves explosive growth is because a large number of the businesses are chasing what really amount to fads This may be the case now but originally the desire for growth was that extreme economies of scale were the primary value driver in electronic commerce/advertising-driven models, thus, achieving that scale was paramount. Over time, the low hanging fruit was eaten and the newer things didn't have such scale, but the desire to invest in a company that succeeded in that way remained, so more and more companies were "forced" to adopt a high-growth model or get left behind by a competitor who did, even if it made no sense. That's how you get Uber being forced to grow at all cost despite having nearly zero economies of scale above the MSA-level. If they got to the self-driving taxi, then they might be able to start realizing that scale, but in the past you had to already be realizing it to get funded.
