In my order from most to least important.

1. A time machine to travel to another time/place. Even though it seems so impossible.

2. Flying cars. Though these already exist but I can't seem to get my head around what air traffic would be like.

3. The ability to preserve, prolong life, replace old body tissues or damaged body parts.

(1). A machine that could teleport humans to a different location at the speed of light.

(2). An invisibility cloak

(3). A machine that could decode and decipher animal language... they have a lot to tell us especially birds and dogs.

No.2 is dangerous in the wrong hands. You could do almost anything without getting caught.

And who said thus don't already exist

l69l:
And who said thus don't already exist

where can I find a time machine? I need to travel to a time when humans were "human"

You're correct

Restricted Access

l69l:

Restricted Access

maybe in a few couple of decades to come. It might be possible.

A machine that could download food.

A machine that could download food.

it seems logically impossible

wis3:
it seems logically impossible

Well, we are wishing...

But.. Remember, impossible is nothing

youngelder:

that's what we tell ourselves. But so many things are impossible.

wis3:

Hahaha... It's only impossible for now..

But never say never..

youngelder:

it is impossible alright. The world is ending and we may not be here long enough to see such inventions made.

Well, the possibilities are much...

I beg to differ that it seem logically impossible.
Have you thought about a food machine using a neural network connected to a main food hub within a geographical range, all you do is login, select the package you want, and get it transported via the conduit connecting your food machine and the main food hub...
Is this logical enough?

It's impossible. Atleasy for the next 5000 years. It is however possible to have a machine that can produce something that looks like food but doesn't take like food, like we have 3D printers with which you could print objects of different shapes, sizes and colors. What makes this difficult is the very complex process food have to go through before they're made. It's hard to make something out of nothing.

You don't seem to comprehend my point...
Think of it as waterboard supplying water with an advance mechanism in place, now relate it to my initial writeup.

I get your point. The most we can get at a point like this is a vending machine like the one below. It could happen it the future though.
