Back then, its illusive nature meant that many believed it wasn’t even a valid subject for scientific investigation.

How your brain creates the feeling of being is the biggest problem in neuroscience. But we are coming closer to cracking it

Today, consciousness is a hot research area, and Koch and Chalmers are two of its most influential figures. Koch is head of the Allen Institute for Brain Science in Seattle. Chalmers is a professor at New York University and famous for coining the phrase the “hard problem” to distinguish the difficulty of understanding consciousness from that of grasping other mental phenomena. Much progress has been made, but how close are we to solving the mystery? To find out, I decided to ask Chalmers and Koch how their bet was going. But there was …
