Technology in the future

So I was thinking people born this year and die at the average age of about 70 will be alive until around 2080  just think of the technology then what will have discovered and how much things will be better. think back 80 years ago the year 1933 the Empire State Building had just finished and hitler had all of Germany ready to strike. The first computers being built and required multiple people to turn on now you do it at the push of one button      

Image how they would think of the international space station and modern tv on all the time and how much smaller electronics have gotten. I find it amazing to think what it will be like in the next 100 years will we have landed on the mars will people be living permanently in space or maybe string theory will be proved and or scientific breakthrough but no one noes what will happen in the future and it might just be good it might be bad like a nuclear war or a plague if you have a different opinion   Tell me in the comments.
