In comparison, US is more entrepreneurial and SV more so - but to be fair, it's more entrepreneurial than anywhere, and even it suffers from risk-aversion and echo-chamber conformity at times.
What do you think?
EDIT I don't think it's a question of tech or not (Australia is technically highly capable and advanced), but of entrepreneurial or not. Our idea of "entrepreneurial" is opening yet another mine, TV station or restaurant.
