Cal Newport

Computer science professor at Georgetown; author of Deep Work and So Good They Can’t Ignore You. Notable for having never had a social media account — argues from lived counterexample, not just theory. Writes 5 books while rarely working past 5 pm, which he attributes to unfragmented attention.

Core positions

• Deep Work — focus is the new IQ; rare-and-valuable output wins markets
• Quit Social Media — social media is engineered entertainment with real harms
• Fragmented Attention Reduces Concentration Capacity

Track record notes

• Initial quality_signal: medium — cites “growing research” without naming studies in this talk; positions are coherent and falsifiable. Revisit as more of his claims meet other sources.
