He's definitely talented and intelligent but as always people vastly underestimate skill. Humour is a skill that you can learn and he's been doing this comic for ages now. When you've been doing something almost every other day nonstop for years, your brain allocates a ton of cycles to that skill. You start applying that skill all the time, sort of like the Tetris Effect. I bet he gets multiple comic ideas daily reading all sorts of research and memes.
I was just saying that banana monoculture combined with specialized fungi could mean that we don't have bananas for much longer, at least not for as cheap as they are now
There's no need to worry. There will always be someone around to point out that prices were cheaper back in the olden days, whether that pointing out is needed or not.
And yes I appreciate the subtle(?) irony in this comment.
(I am pointing something out. (Which these parentheticals are also doing.))
