how do you think these things will change in 50years?

Sports:

Professionals will be more athletic than now, equipment safer, balls travel faster, defense will be less of a contributing factor than it currently is.

Military:

Wars will be fought with drones and other machines more often than with people. More bombs less guns. Faster vehicles.

American education:

Highschool will have individually chosen courses that a student chooses based on his or her own interests. Schooling online will be much more common than it currently is. College will be cheaper.

Japanese trade in exporting zones:

I am not educated enough on the topic to predict this one

Composition of music:

Unsure. An entirely different genre will have developed by then, I am unable to predict what it is. We will see less live performances though.

Cars:

Faster, more fuel efficient. Speed limits will be increased as the simplicity of controlling your vehicle increases. Safer cars, tires with phenomenal traction, built in GPS to all cars, very comfortable seats, much more space in the vehicle.

American Football will be as odd as ever...making millions of $ just because some guys can play ball...

And cars will hopefully become more green.Maybe a solar car or a vegetable oil engine will arise.

I see two important choices in this post.

I could help you and thus pass you through school, only to have to fail miserably at life.

Or, I could not help, and then I could see you blossom into a lovely knowledge-flower.

Both are rewarding in different ways.

We would be whipped off the earth by technology by then.

Robotic Biological Humanoid Technology is an Abomination to the LORD GOD.

-Composition of music

Well let's see, looks like we went 10 steps backwards in terms of writing good music.
