Why AI has no taste and how to fix it (w/ Thais Castello Branco) | E2319

This Week In Startups is made possible by: YSecurity https://YSecurity.io/TWIST MongoDB https://MongoDB.com/ai Odoo https://Odoo.com/twist Today's show: AI models can solve PhD-level math equations and code an app in minutes… So why does everything they design look like identical slop? Thais Castello Branco, founder of Taste Labs, raised $18.5M in seed funding to teach frontier models about aesthetics and outputting quality content. She talks to Jason and Lon about why even frontier models regress to the mean on subjective tasks, how paid "TasteMakers" can improve output quality, and whether AI accelerates or destroys the half-life of "what's cool." PLUS Leopold Aschenbrenner's AI hedge fund liquidated its public stock portfolio, but it may be too soon to count this 25-year-old completely out. Google Earth adds AI generation and turns into a misinformation factory. LinkedIn and Substack join the AI slop crackdown. And why does every venture capitalist seem to have an opinion about the Ceuta border crisis?
