You've hit the nail on the head though - "educated". Perhaps unfair, but I find it hard to believe that people making guesses on these items could be genuinely educated regarding the issues surrounding them.

I completely include myself in this category - what do I know about the logistic changes needed to change manufacturing for some of these devices, or market demand etc. I can speculate regarding the technology, but even then it's just speculation based on a totally superficial understanding. It's so easy to ignore things like FDA approval, production scale up, resource shortages etc.
