  A 4 year old child has 16k wake hours x 3600 s/hour x 1^6 optical nerve fibers x 2 eyes x 10 bytes/s = 1^15 bytes (approximation by Yann LeCun).

  Processing visual input is the current bottleneck for robots that want to make sense of the physical world. Glad somebody's looking into it (no pun intended). I just hope their plan is more sophisticated than throwing more computational power at the problem.

  Why is OpenAI investing in startups? They invest 100 million in another as well. I thought OpenAI was building their own things as a non profit, why are they investing? Is it normal for non profits to invest like this? Do they lack confidence in their own stuff, do OpenAI have too much money they don't know what to do with?

  "Norwegian humanoid robot startup 1X Technologies recently raised $100 million with backing from OpenAI"
