Too Short for a Blog Post, Too Long for a Tweet LXXI

Here's an excerpt from a book I recently read, "The Sleep Revolution: Transforming Your Life, One Night at a Time," by Arianna Huffington:

“Basically a machine that sleeps and dreams learns more and performs better in the long run than one that is always awake. What it means for a machine to sleep is to essentially switch off its direct connection to perception and action, while to dream means to repeatedly replay experiences in order to extract the maximum learning signal from them.” As Hassabis told me, “It is a paradox. We think of sleep as an inefficient use of time, and in fact it is the most efficient use of time in terms of learning and memory.”
