The assumption being that its easy and should just be a 'given'. The problem is with that and not proper testing/validation you can have false confidence in the systems.
The article is actually really interesting, but it's exception, it's certainly not impossible.
I have made no such assumption. The person who I was responding to said it is not possible. I said it is possible to do. That is all the claim I'm making.
Of course it is very hard. It is kinda implied by the fact that I linked an article about the technical challenges! If you order some custom built equipment and the company then later writes an article about all the challenges with it, you can bet that it was a super expensive and specialist device.
What assumptions have I made and how would they lead to disaster? Please be specific.
