In the past, economies were driven by human labor, by land and its resources, by financial capital, or by infrastructure.
Technology is different.
Technology doesn’t require land, it can replace resources, and it doesn’t require massive amounts of low-skilled labor. Singapore (right), Hong Kong, Israel and Silicon Valley have none of these things.
What these and other tech centers have, is trained minds in abundance. They can create them. They can attract them. They nurture them. They give them what they need to thrive.
