Yeah, anyone who uses taxi drivers as an example of destruction either don't know what they're talking about (because they never experienced it) or they're crying crocodile tears.

I had cab drivers nearly drive off with me hanging off the car in San Francisco, because they were far more concerned with screening my destination than, say, not killing me. If Uber destroyed that industry, it was only a net benefit to society. They created immense value, and the "destruction" was only to eliminate a layer of corrupt parasites who made money by preventing a free market (in this case, the medallion owners, but the entire industry was corrupt from top to bottom).
