| I used to consider Tononi as the best philosopher of consciousness until I learned more about neural nets and watched the RL course [1] by David Silver (co-author of AlphaGo). After I understood the RL paradigm, I realise that Tononi's explanation barely scratches the surface. Yes, there is integrated information, but how does it come about? What is its purpose? The answer is simple - painfully simple - the goal is to maximise rewards. One goal we all have is to live and have children - and this root goal (a necessity of the genes to propagate, actually) is what guides the evolution of integrated information in the brain. But the environment plays a crucial part in the contents, structure and complexity of consciousness. Integrated information is very dependant on the environment. Yet Tononi & co. still search for it in the brain, as if you can speak of a brain without considering its experiences, and consider experiences without thinking about the world and the problems the agent has to solve. Just watching reinforcement learning agents learn and evolve in simulated environments, as we had the opportunity for the last 3-4 years, is enough to create a perspective about agents that is not human centric and that is very useful in thinking more clearly about consciousness. You can see a humanoid learn a gait that is like the Ministry of Silly Walks [2], you can see bots playing FPS games, AlphaGo playing against itself, cars driving themselves... That puts human learning and human agenthood in perspective. [1] https://www.youtube.com/playlist?list=PL7-jPKtc4r78-wCZcQn5I... [2] https://youtu.be/g59nSURxYgk?t=88 |
