>But I wonder if a city could ever follow the model of Atlanta and try to build a "new Silicon Valley" from scratch with aggressive policies that lure companies/employees from existing tech hubs? It's totally possible. I think the problem right now is that for profitable tech companies, right now engineers are still super cheap (like most of big tech makes rather more than 500K per employee, and pays less than $250K.) - from that perspective, it doesn't really make sense to try to save money on employees... the opposite, really. If they have to pay another $100K/head 'cause the cost of living is so high, that's a smaller bite than anything that might disturb the massive profit. (this is also the root of the argument that we should unionize, even though we make silly money compared to most other workers. Facebook captures a lot more of the surplus value created by labor, say, than Walmart does, even if by any other reasonable standard, we are treated so much better than a walmart floor associate. I mean, I'm not arguing for or against unionization, I'm just saying that's why some people want to unionize even though we already are better off than nearly any other class of worker.) The other thing to think about is Detroit. Detroit was totally one of these cluster cities; it was the place to be if you were working with cars in a period when there was a lot of innovation to be had in cars. And then the industry changed (or rather, innovation slowed a lot... like, there just wasn't that much more you could do with cars; just small incremental improvements) - automobile manufacturing scattered to the wind and Detroit is kind of a husk. Will that happen to the software industry? will innovations start being small and predictable? will the P/E of Facebook drop to match the P/E of Ford? I mean, silicon valley has already been through one of these changes; silicon valley is called silicon valley 'cause they used to make the silicon here, and they've really successfully switched to writing software. I mean, I'm personally long silicon valley (and while I think it's overvalued now, I think it's a good long term bet) - I think it will turn out more like New York than like Detroit, but... who knows?
