I am an educator and neuroscientist who studies how the brain learns to read and what happens when a young brain can't learn to read easily, as in the childhood learning challenge, developmental dyslexia.

The act of learning to read added an entirely new circuit to our hominid brain's repertoire. The long developmental process of learning to read deeply changed the very structure of that circuit's connections, which rewired the brain, which transformed the nature of human thought.

There's an old rule in neuroscience that does not alter with age: use it or lose it. It is a very hopeful principle when applied to critical thought in the reading brain because it implies choice.

Deep reading refers to a whole continuum of processes that include some of the most important things about thinking and how we connect thought to what we read - critical analysis, analogical reasoning, how we infer from the text, how do we take another's perspective.

A molecular manufacturing technology will let us build molecular surgical tools, and those tools will, for the first time, let us directly address the problems at the very root level.

The problem of forgetting might not torment us so much if we could only convince ourselves that remembering isn't important. Perhaps the things we learn - words, dates, formulas, historical and biographical details - don't really matter. Facts can be looked up. That's what the Internet is for.

The success, or failure, of a CEO to implement AI throughout the organization will depend on them hiring a leader to build an organization to do this. In some companies, CIOs or chief data officers are playing this role.

Facebook are an amazing team, a brilliant team. It's a technology that brings people together.
