A leading neuroscientist claims that a pongplaying clump of about a million neurons is "sentient". What does that mean? Why did Cortical Labs teach a labgrown brain to play pong? To study biological selforganization at the root of life, intelligence, and consciousness. And, according to their website, "to see what happens." What's next for biocomputing?

The cells aren't directly frozen in liquid nitrogen they are put in vials and stored in liquid nitrogen (and you can't buy them legally without credentials) https://www.atcc.org/products/pcs201...
The sentience of some invertebrates, like octopuses, is generally agreed upon. Prominent scientists affirmed nonhuman consciousness in the Cambridge Declaration on Consciousness: https://philiplow.foundation/consciou...
The "Neanderthal neurons" are human cells that are "Neanderthalized" using genetic engineering:    • CARTA: Imagination and Human Origins:...  

DISCLAIMER: The explanations in this video are those proposed by the researchers, or my opinion. We are far from understanding how brains, or even neurons, work. The free energy principle is one of many potential explanations.
