HIGHLIGHTS FROM THE EPISODE:

• AI is most effectively being deployed first in customer service where outcomes can be clearly measured and tracked.


• Return on Equity (ROE) has become less relevant in modern markets where companies can easily raise capital and buy back shares.


• Google has evolved from being criticized for sitting on cash to making aggressive investments in innovation, as demonstrated by Waymo.


• Tariffs function as a transfer mechanism from consumers to workers, potentially helping build strategic industries despite some economic inefficiency.


• While passive investing continues to grow, there will always be a cyclical role for active trading to enable price discovery and market making.


• Meme coins and app-based stock trading represent newer forms of gambling that might be more socially beneficial than traditional sports betting.


• A new book reveals Buffett's early investment strategy combined detailed research methods with an evolution from pure value investing to investing in quality companies.
