The only difference between science fiction and science is patience.
Yesterdays mainframes are todays smartphones and todays neural networks will be tomorrows androids.
But long before any technology becomes reality, someone has to dream it into existence.

The worlds of science and technology are constantly in flux.
Its impossible to tell what the future will bring.
Medical nanobots
This could very well be the most important technological breakthrough in human history.
And this wouldnt necessarily mean filling your bloodstream with trillions of microscopic hunks of metal and silicon.
Fusion power and quantum optimization
Another technology thats sure to save innumerable human lives is fusion power.
And thats when we can finallystartsolving humanitys problems.
And thats where quantum computers come in.
We could assign algorithms to every living creature in the known universe and optimize for their existence.
In essence, we could potentially solvethe traveling salesman problemat the multiverse scale.
Warp drives
Admittedly, warp drives are a glamour technology.
Technically-speaking, with Mars so nearby, we dont reallyhaveto travel beyond our own solar system.
But its well-documented that humanity has a need for speed.
The big problem here is that the universe doesnt appear to allow anything to travel faster than light.
And thats pretty slow.
It would take us over four years to travel to the closest star to Earth.
In galactic terms, thats like spending a 1/20th of your life walking to the neighbors house.
Warp drives could solve this.
If aliens arent right next door, then maybe theyre a few blocks over.
The metaverse (no, seriously)
Dont laugh.
Its understandable if you dont think themetaversebelongs on this list.
But the metaverse of 2100 will be something different entirely.
The ideal metaverse would be a bespoke environment thats only indistinguishable from reality in its utopianism.
In other words, youll only know its fake because you could control the metaverse.
The ultimate freedom is choosing your own reality.
