your comment is no better than op's. you could provide some examples why his opinion is wrong, because i believe quite a lot of people (myself included) think that most of companies that only exist in silicon valley are about extracting money from markets that are essentially driven by fashion.
You are right, I should have made a better comment or no comment at all.
I'm just tired of the obviously incorrect proposition that Bay Area is producing just frivolous photo sharing and social communication tools (which both has a huge value for humanity, but that's a different story) and I seriously find it an interesting thought experiment what would happen on a global scale if the Bay Area would be devastated by a big earthquake.
The obvious tech giants like Google, Apple, Oracle and Cisco are arguably supporting a huge number of businesses and organizations around the world. But a glance through a list of just publicly traded US SaaS companies reveals that about 40% are from the Bay Area. These offer SaaS-based solutions ranging from HR tools (Workday), IT service monitoring (Splunk), ITMS (ServiceNow), CRMs (SalesForce), ERPs (NetSuite), Insurance backends (Guidewire) to supply chain management (e2open), to just name a few.
If Bay Area suffered anything resembling 2008 Sichuan earthquake, it would halt a good part of the economy for a while.
