'Thinking' Robot with Neurons Grown from Living Brain Cells is Taught to Steer Around Obstacles: “A robot developed by researchers at Japan's University of Tokyo was equipped with brain-like neurons to teach it to think. The compact robotic vehicle was connected to a culture of brain neurons grown from living cells and placed in a maze. Said the researchers, "When the robot collided with obstacles or when its goal was not within 90 degrees in front of it, an electrical stimulation from an electrode was applied to the culture." Homeostatic signals fed to the robot let it know it was moving toward its goal, but this homeostasis was interrupted with disturbance signals in the presence of an obstacle, prompting the robot to recalibrate.” https://www.dailymail.co.uk/sciencetech/article-10132249/Japanese-robot-uses-neurons-grown-lab-avoid-obstacles.html

Robin Hanson: “My challenge to socialists: show how proposed socialist processes, such as workers voting on managers or capital allocated by govt agencies, could work remotely as well as does Marcus Lemonis in The Profit, & I’ll pledge my allegiance to socialism.” https://www.overcomingbias.com/2021/10/the-profit-socialism-challenge.html
