Here's an example I posted on twitter, from Boulder, Colorado:

That seems like a pretty absurd historical designation. It's just creating a burden for the people who bought it. It's a far cry from bulldozing a beautiful old brick building to put in a McDonalds.
Edit:
> The empirical evidence suggests you cannot be too strict about historic preservation. The tougher cities are about it, the better they seem to do.
If you go a bit beyond the US, you could look at Europe and... I'm not sure that's true. Rome has a ton of old stuff that's been reasonably well preserved. Berlin has been torn apart and reinvented. Berlin is doing way better than Rome in terms of startups.
Granted, there are a ton of other factors in play, but if it were just about having a lot of historical stuff, Italy would be the startup capital of the world.
I think I get what he's talking about... you want architecture and places that feel 'real', not some homogeneous office park. On the other hand... most of Silicon Valley is very new, and not very exciting, and it did "ok".
