3. @Jason noted that AI model updates are too rapid for users to keep up, calling for headless apps that automatically switch models and focus on killer integrations. He also highlighted that AI token costs are hard to monitor, causing CFO dissatisfaction. — via 1 2
4. Lyn Alden argued against a pause on AI development, calling it a 'luxury belief,' while Marc Andreessen questioned 'why China wouldn't do it.' Both emphasize that AI is built on decades of semiconductor deflation. — via 1 2

3. @Jason argued that high-value lawyers ($1000/hr) are safe, but low-value ones ($300/hr) may be replaced by AI; law firms should adapt. — via 1
