Someone said that as startups moved to city X, that city was experiencing an “innovation multiplier” effect.
Creative people built businesses in that city, bounced ideas off one another, inspired more ingenuity, and ultimately generated even more innovation.
This is similar to Network Effects.
The more innovation in your city/community, the more innovation will follow.
Therefore, if you want to become a great creator (whether in business or any other creative endeavor), it seems crucial to join a community of like-minded people.
