It's puzzling that as we verge on gaining actual understanding of the human brain that goes beyond the very simplistic, there are people who expect that too much biology may be the problem. This thing is just getting started. It has mostly failed because we still don't understand the organ that is being studied.
As opinion goes, it's right there with saying that the phone is interesting and all but the technology has pretty much peaked in usefulness... right on the cusp of the computer industry beginning to work on telecommunications. Or finding the steam engine interesting but otherwise saying mechanics will be of little utility in the future, based on how little they were before being mastered.
If anything, it highlights the fact that it's nearly impossible to solve a medical puzzle until you actually understand its mechanisms, that just winging it with guesses and basically coming up with some opinion at random and just rolling with it obviously yields poor results. I just don't understand how people can say it's been a failure to understand disease of the brain while we still barely know a damn thing about how it works at all. Learn to walk. Then learn to run. Don't write off the toddler that's just beginning to walk steadily as never going to be able to run based on current wobbliness.
It's not as if alternative approaches will have anything new to offer. Non-biological approaches today are still exactly the same as they were a full century ago: think happy thoughts and don't not think happy thoughts. Technology isn't going to make any difference here, unlike what an actual understanding of the brain will do.
