Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and Ideas

Artificial intelligence is everywhere around us. Deep-learning algorithms are used to classify images, suggest songs to us, and even to drive cars. But the quest to build truly “human” artificial intelligence is still coming up short. Gary Marcus argues that this is not an accident: the features that make neural networks so powerful also prevent them from developing a robust common-sense view of the world. He advocates combining these techniques with a more symbolic approach to constructing AI algorithms.

AMA | February 2022

Welcome to the February 2022 Ask Me Anything episode of Mindscape! These monthly excursions are funded by Patreon supporters (who are also the ones asking the questions). I take the large number of questions asked by Patreons, whittle them down to a more manageable size — based primarily on whether I have anything interesting to say about them, not whether the questions themselves are good — and sometimes group them together if they are about a similar topic. Enjoy!

185 | Arvid Ågren on the Gene’s-Eye View of Evolution

One of the brilliant achievements of Darwin’s theory of natural selection was to help explain apparently “purposeful” or “designed” aspects of biology in a purely mechanistic theory of unguided evolution. Features are good if they help organisms survive. But should we put organisms at the center of our attention, or the genetic information that governs those features? Arvid Ågren helps us understand the attraction of the “selfish gene” view of evolution, as well as its shortcomings. This biological excursion has deep connections to philosophical issues of levels and emergence.
