I wasn't initially moved to respond to this article. But I wanted to "weigh in" after reading some of the initial responses.
I was at Automation Fair '07 when one of the presenters discussed the approach of allowing multiple control architectures "in house." As I looked around the room to see the general response, via body language, I saw some people nodding in agreement and others laughing off this suggestion. As I talked to some people it seems that most of the people that were laughing off this suggestion were "plant level."
