Ok, if I notice other devs suddenly getting 5x as productive I'll give it a try, but so far no such effect has been demonstrated. It seems like a pretty straightforward research question, and you'd think if there was any demonstrable effect the companies selling these things would use such research to market their products. So where is it?
There's a dead body lying there but you won't believe they're actually dead until someone creates a video reenactment of the killer stabbing them and shoves that video in your face?
