Couldn't agree more. Although to be more precise, ETH/ICOs are threatening the standard financing model proper in Silicon Valley, and not SV as a whole.

I basically see the future as being both really dystopic and utopic at the same time:

So (mostly rich) people will be able to invest their money without any friction, but this will destroy the rent-seeking institutions that weren't meant to exist in the first place

=> power to the geeks and the rich, but you won't be able to make any money by just making "deals".

Would love to be convinced otherwise though....
