Coinbase CEO Brian Armstrong has urged the United States to create Special Economic Zones akin to those in Shenzhen, Hong Kong, Singapore, and Dubai. Speaking on the Relentless podcast, Armstrong emphasized that these "innovation sandboxes" could significantly boost industries such as cryptocurrency, biotechnology, and drone technology by reducing regulatory barriers. He also envisions a future where such zones could evolve into cyberpunk-style free cities, fostering rapid technological advancement.
