Paraphrasing the article: If you connect a GPS to your small or large aircraft's autopilot and you use it to fly from A to B without having a human pilot ready to take over at any point you are a) breaking the law and b) going to die sooner or later (well, we all do but you know what i mean). To make GPS a system that is aerospace-grade safe is not possible today. But everyone with a pair of eyes can legally and safely pull off the same feat. So to replicate that feature you have to somehow bring computer vision to the level of aerospace-grade reliabilty. I think that's what the author was going for here.
