Why are people even spending money on this research? What are they trying to prove/disprove?
"This research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors."
That it takes much fewer than infinite humans and infinite time to produce the most pedantic paper possible.
Not to mention that frivolous research has been known to pay surprising dividends.
Still, it's a very bizarre assertion to make; it's like they're trying to debunk something that no one claimed.
ETA:
Maybe they were trying to prevent the Mr Burns' of the world from trying to experiment: https://youtu.be/no_elVGGgW8
(but try telling that to The Grauniad!)
