Probably a teleportation device. It would be so incredibly useful. And you could make a crap ton of money as a delivery service if you had a teleporter.
You know.... We probably could do alot of this stuff.... But science said we needed seedless watermelon. So we spent time and resources and developed seedless watermelon. Now we have that instead. Food for thought.... Literally.
Sadly, my mind wandered immediately to something that would make one impossible fetishes realizable. Then I read the cancer-curing machine suggestion - that's much, much better and humanitarian. Or perhaps something like warp drive
Out of everything. A device that generated food for the homeless/starving. A device that can cure all diseases. A device that contained all knowledge about the universe. Technically the last one is all you would need. If you had every single piece of knowledge you wouldn't need anything else because you would know exactly how everything works, and exactly how to fix/do everything... But no... you want your cock to be an inch longer. LOL. It would probably look like a piece of play doh after if you stretch it too much.
Oh! I thought of another one today! I would absolutely die for a device that reads my thoughts and writes then down for me. As a writer, I ALWAYS seem to come up with my best stuff while I'm working or driving or something, and then by the time I get around to writing it down, I usually can't remember the exact phrasing I came up with earlier.
It's hard to understate how dramatically teleportation would impact the planet. Transportation, oil & gas, and real estate would be rocked ... and while it would be amazing for shipping, first responders, etc., it would also enable human trafficking, drug cartels, illegal immigration ... can't imagine how much it would change things.
I think most porn addicts would rather create a time machine so they could make sure this thought-recording device never sees the light of day, lol.
I'd like to invent a passenger jet where the whole fuselage opens so everyone can board at the same time, instead of in that annoying single-file line where we're all at the mercy of the one idiot who can't figure out how to put his bag in the overhead.
Oh, don't get me wrong, I think it would be amazing. I just think it would be insanely disruptive. Just think about real estate alone: you could live literally anywhere you wanted in the world, and it wouldn't matter how far you were from your work, or your gym, or your school, or anything else. You could work all day in New York City, meet your friends for happy hour in Hollywood, and then return to your huge farmhouse in rural Nebraska. Home prices and rents in big cities would plummet.
ok. two penis stretchers. One for me and i'd loan the other one out to my good friends...and the homeless.
I have a feeling that if you gave penis stretchers to the homeless that actually worked... they would join the porn industry... you would doom humanity.
