Have all the good ideas already been discovered?

Josh and Chuck dive into a fascinating question that's puzzled thinkers for centuries: have we run out of good ideas? Starting with the mind-boggling fact that it took humans 2 million years to figure out how to put handles on stone tools, they explore whether we're still innovating or just repackaging existing technology in sleeker designs. The hosts examine cutting-edge research from UCLA scientists working on everything from cancer-detecting nanomaterials to brain circuits controlled by light, while grappling with deep philosophical questions about the limits of human discovery and whether our subjective reality prevents us from ever truly understanding everything.
