I think we might have really advanced technology and that we would be in a much better environment than we are in now. So we would have maybe hologram computers, people living on other planets, hovercrafts, stuff like the ones you see in Star Wars or other futuristic shows.

not much wouild be diffrent mabey a few new gadgets ... but thats it

No, it'd definitely be more than just a few. look up the butterfly effect. It'd either affect it very little because the computer was never studied or it would affect it A LOT

just like the movies i watched the future will totally change when we change something in the past , if that would happen out technology will really upgrade and maybe we will have a flying car now

The funny thing is, all of our computers are time travel computers already. That's kinda what happens every time you get information stored in another time zone.

That would end up with a paradoxical twist. Technology would advance quicker so they wouldn't time travel in the first place because someone would have done it before them.

We wouldn't be sitting here using computers the way we do right now.
Would be interesting to see what would be left in life that you couldn't do with technology.

we be asian.

I think it could possibly screw up the timeline so badly that by 2025 we'd be plunged into World War 4.

Or...

We'd be living in a 2055-style society. Peaceful and high-tech. Maybe even flying houses.
