If you can build something for $100, yet the same thing they used costed $250,000 to build, ok let us even say for good measure it costed $25,000 and the rest was inflated, compared to $100 it must be a well awesome product, way superior than what you could build, ten times, 25 times, and if we are to trust the actual figure, 250 times better than what you could built.
The point of the article is most probably that it is the latest technology anyway. I mean, it is fine to look out for these flaws, but something much grater happened there, they actually discovered something. If all we get from comments is flaws flaws and the opposite down voted, then this community simply is not working.
