Normally technology is advanced during war, but even with war something like this takes a long period of time for even minor discoveries to be made.
Lemme see what progress we profited from the previous wars:
Early Computer
Mobile phone
Jet engine
Internet
Satellite
Kevlar
Radar
Laser
Night Vision devices
Medicine
and many more.
Sad to say that mankind progress much faster through death and destruction.
This War on Terror didn't give us much (visible) progress in technologies, and now it have been going on more than a decade.
OK, now we need another war with both side equally strong, just to get more progress.
Just look at WW2, within 6 years, we reaped lots of technologies from it.
OK, sorry for straying waaaay out of topic.
Here's a question, if there is a time machine and time travelers, how many of our histories have been changes right now? We might not even notice it, unless we're the one that do it.
Let say that one of us travel back in time, and
erase the
ASF founder(s), would we be around here right now discussing about time traveling? No, we might discuss this probably on other forum site, and we wouldn't know that ASF ever exist.
The only way for us all know for the time travel is possible is when somebody in present time goes to the future and bring back some future technology for us.
Personally, I rather travel to the future rather than the past. IMO it's would cause less damaging effect to us.
