If you could innovate one invention, what would it be?

Right now I’m thinking either making toilets flush quieter so you don’t have to worry about waking anyone up or making anti-nuke devices basically invisible because I think it’s ridiculous that there are bombs that can wipe out half of a continent in one hit. I mean seriously, why do mostly normal and relatively innocent civilians have to pay for some politicians bullshit? Imagine how many lives would be preserved if world leaders just took out their frustrations on each other in a ring instead of having thousands upon thousands of their own people going out and semi-murdering other random people. Imagine prevailing against inflation and gay mafia movements just to get drafted into WW3, this is bullsh*t.

Actually nevermind, I would innovate artificial foods so that they’re actually nutritionally beneficial so that you don’t have to eat triceratops throw up like a f*cking rabbit to be healthy. Imagine getting vitamins from a Twinkie or something.
