The man who invented the web is aware of the many issues it faces, from problematic social media use to the rise of unfettered AI. He also has a plan to remedy the situation

Computers built with analogue circuits promise huge speed and efficiency gains over ordinary computers, but normally at the cost of accuracy. Now, an analogue computer designed to carry out calculations that are key to AI training could fix that

During sleep, your brain cleans itself by flushing through cerebrospinal fluid to prevent damage to brain cells. If you're lacking in sleep, this happens when you are awake - and seems to cause momentary lapses in attention
