I just submitted it and was lucky. It's the kind of thing that sub likes. I've had around three posts hit the front page out of probably thousands since I started, there's definitely a large luck factor that goes in.

We're consequentialists here, so I get all the credit for it even if it wasn't much effort, right?

By the way, looking at https://www.reddit.com/r/Futurology/duplicates/4vhqoc/should_we_wipe_mosquitoes_off_the_face_of_the/ there are another couple submissions in other subs right after mine which were presumably inspired by my post (the article is from February), one in TIL which also hit the frontpage.
