When they claimed "Gödel’s findings may seem rather obvious" that kinda put me off of the article. Obvious to whom? It wasn't obvious at the time and I'm sure _most_ people haven't even heard or thought about the problem before.
Maybe the wrong version of Godel's findings that the article states seemed obvious to the author. Lots of complex questions have simple, obvious wrong answers.
Having had a need for nano positioning in the past I really try to avoid PI like the plague. Bad and slow sales people, opaque pricing, no way to test their product before they expect you to lay down 50k. Bad integration with other tools.
