It's impudent to Vancouver's culture--and more generally the world--to insinuate that we're "blindly [competing] to build the next Silicon Valley". We're not. Canada's not. Vancouver's liberal lifestyle is innate, not superficial, not a failed attempt to clone Silicon Valley. And our immigration policy is definitely not to "bring immigrant entrepreneurs together"; it's the result of a small population, the demand for skilled workers[1], and the correction of a historically xenophobic foreign policy. This creates a large influx* of liberal and skilled immigrants--known risk takers. Hence the entrepreneurial honeypot (our social programs help). It's necessity that's bred Vancouver as a technological center, not ambition. Thus, similarities to Silicon Valley are purely coincidental, or are the result of correlated effects rising from the increasingly entrepreneurial working force.
As for investors? I don't know enough to comment.
