On May 26, 2026, marketer George Mack published a Substack newsletter exploring astrophysics. While George Mack is looking to the stars for inspiration, the tech podcast world is still obsessed with his down-to-earth productivity hacks.
On the podcast My First Million, host Shaan Puri pointed to George Mack as a prime example of someone fighting phone addiction with extreme measures. Shaan Puri explained that "George Mack has two phones, one's a smartphone, one's a dumb phone", highlighting the "gargantuan" challenge of screen time that everyone in tech is currently desperate to solve.
The debate over how to cure digital fatigue is only growing. While some builders opt for software blockers, George Mack's physical separation of devices represents a more radical, analog approach. As his newsletter moves into more abstract intellectual territory, his practical lifestyle experiments remain a foundational reference point for creators trying to claw back their attention spans.
