Why does most innovation happen in cities?

Because that’s where most collaboration between people gets done.

Cities are collaboration engines.

Lone geniuses, although a great romantic tradition, are mostly a myth. Even the most individualistic of creative souls will surround him or herself with similarly or even more talented, and industrious people, in order to make stuff happen.

This is basically the gist of Walter Issacson’s book, “The Innovators”.

So, get out and let the city you live in inspire you to innovate!
