Ah the grandfather paradox but instead of killing your grandfather... "You killed Hitler, now you don't exist."

I appreciate your optimism! It's nice to see views from someone who has a shred of hope for humanity haha!

A perfect future would be a dream come true, considering the current state of the world! However, I believe we're more inclined towards extinction to be honest. With great power comes great stupidity!

That is a very valid point!

Technology has advanced incredibly quickly, however I don't think we're at a point where we can manipulate physics to our will within any of our lifetimes. The very fact that events such as the Holocaust haven't been prevented gives me reason to believe we will never find a means of time traveling into the past. You know what humanity is like, SOMEONE would have killed Hitler in his youth. There would likely also be very strict policies on who could use it and how it could be used so I doubt the general public would ever have access to it. Maybe time travel into the future could become a possibility though, assuming we don't wipe ourselves out anytime soon. ♡
