seems pretty easy to build, not many obstacles are in the sky. surprised this was a break through at all...

this just feels like a video game basically. all i need to do is bring out my xbox controls and i can do exactly the same thing in my video games.

AFAIK, the technology isn't really anything new (see drones), but I took the article to mean that the "breakthrough" was in doing this safely within civil airspace. My use of scare quotes is really just because it's the first time (in the UK, don't know about elsewhere); it's more of a milestone than a breakthrough.
