They already are GMOs, that word is rubbish and so highly misunderstood and misused. Selective breeding (and probably cloning plants, like nearly all bananas) is genetic modification, whether it originally is random mutation or not...modifying outcomes by choosing for specific genetic variables means GMO. Every single thing you eat is GMO.

Semantics aside, no one seems to take this seriously, it's wild that one of the cheapest and most sold fruits in the store will likely not exist as we know them in the "near" future. There are other, resistant bananas that probably even taste better, but are less Shippable, so banana prices will eventually increase to cover that increased complexity.
