Ex-Lehman Trader: AI Won't Give You Edge

AI and agents compress trading R&D cycles but human execution discipline, not technology, remains the true source of market edge.

• AI won't create edge: Yokokawa argues LLMs and agents shorten the R&D/backtesting loop but execution still requires disciplined humans, since "agents don't pay tax" and humans bear the risk.
• Developer growth 4x in 6 months: Alpaca's monthly active developers grew from roughly 20,000 to 80,000+ in six months, which Yokokawa says outpaces even Anthropic's growth rate.
