After a week or so of hob-nobbing with the elite Don Tapscott wraps up with a final column on Davos talking about brain science. Or, more accurately, funding for brain science. "The research invested in understanding mental illness is starting to catch up with the size of the problem. Over USD $7 billion is committed world wide to understanding the brain with more commitments weekly." That sounds like a lot of money, but it isn't, really, not on a world-wide scale. Also, I don't like the machine-language used to describe the brain - a "parts list" and "bipolar disorder and depression as circuit problems." Humans may be material beings, but they are not machines; they are much more complex than that.
