Honestly,
This Video has completly changed how I view trans humanism. Previously I was thinking along the lines of a Deus Ex future where we might have some subdermal implants to make us stronger, maybe prosthetic eyes and such.
But now this is the future I imagine: You go to work and "plug" into a system that allows you to control several robotic features at once, perhaps you're a pilot or just sitting at your desk remotely controlling a few computers. After this you drive home from work, using a semi automated car that can read your thoughts to get directions and execute those directions autonomously. With a simple task like cooking, you might be able to do remote controlling (the latency of a few seconds in cooking isn't a big deal where it might be for driving). You can drive home controlling a few robotic appendages.
As we progress through this a few things start to happen: The robotic systems we control become more abstract. We start with body analogues (arms, legs, humanoid robots) and move on to more abstract things (controlling computers, cars, and things that aren't analogous to the human body at all). Also, our brains start to adapt to work more parallel and less serial. We're already seeing our behavior move in this direction with the rise of multitasking. We might engineer our brains to be more effective multi taskers, or just let evolution do its thing.
And the end game comes down to people having control over the world around them from the mind instead of the body. Even if it turns out it's impossible to send stimuli directly into our brains like in the Matrix, we can still imagine a future where a single person can use their brain to control several spy drones, telling a system to make suspicious images bigger, to quickly switch between different cameras, telling them to look different ways and such. I imagine a world where machines aren't implanted to our bodies but instead our heads.
Imagine the first person to fully control enough limbs to play a symphony, to preform a dozen person ballet. Combining these with smart programming and you wouldn't even need to know how to physically do either of these things, just know the sounds you want and the movements and the program can interpret them.
All I can say is that i hope the future is at least half as awesome as this.
