I think it's worth pointing out that this story crops up every few years and it is always sensationalized. Not saying it couldn't be a problem but I think people read too far into it.
Among other things the Gros Michel banana is not extinct. It is just no longer in large commercial production. It was easy to start growing Cavendish bananas then deal with the root rot.
I’m kind of surprised we don’t have other flavors.
I’ve seen the red minis but a bite sized fruit is not worth trying. Maybe there’s no reason these should be different than say grapes, but eating a bunch of grapes is “normal” while eating a bunch of bananas looks like a pain in the ass.
Plantains aren’t really the same and need some preparation. Again, not a convenient snack.
Give me a different banana of a similar size and A small multiple of price and I’m there. I pay at least double what I need to for beers, chocolate, ice cream, etc, so likely could be persuaded an interesting banana is worth more
Fun fact - artificial banana flavoring tastes more like the Gros Michel banana. So when you have banana flavored candy, you are tasting what a banana used to taste like back when the Gros Michel was the dominant banana variety.
