While rising rents in SF/Bay Area are due to more & richer tech people, overall costs are declining thanks to tech companies. The cost and reliability of taxis is much much better with Uber than it was previously. The cost of many goods that one has access to is lower via Amazon for so many people. A lot of local businesses are probably more profitable working with Google than they were previously with the Yellow Pages. Yes, there will be spectacular failures, but right now 3 of the 5 most valuable companies in the U.S. did not exist ~21 years ago (Google, Facebook, Amazon), and 1 of the 5 was a tech company which many had written off (Apple). It's easy to laugh at the failures, but the real entrepreneurs just don't care. I don't think Larry Page or Jeff Bezos minds if you want to laugh at them over Google Knol or the Amazon Fire phone. For their 100 failures, their one big win was with no doubt worth it e.g. AWS or Android.
