If I ask my Chevy dealer to run a diagnostic on my Honda, then take it to a Ford dealer to fix the brakes and a Lexus dealer for the transmission, I am likely to end up with a dysfunctional car. And that is for the most common machine on the planet. Straight, human engineered mechanics.

I believe we already have many a system such as you described, with enough variations to keep us all eternally confused. Ya gotta pick one and make it work. Gotta have Faith and work your chosen approach.
