"My mission is to build technologies that can't lie." That's @profdanklein on this week's Gradient Dissent. Dan is a Berkeley computer science professor now building Scaled Cognition, a company designed around one bet: that reliability is the part of intelligence that's been left behind. @l2k and Dan get into why ChatGPT is always confident even when it's wrong and how Dan is working to fix this at the foundation.
