Dude, who says we don't already have time machines? Maybe the government's been using them for years, and we're living in a reality that's been shaped and reshaped by time travelers. Wake up sheeple, we might be in the matrix!

We should consider the moral implications of time travel. The first major change shouldn't just be something whimsical like getting rich. What if we could prevent atrocities or warn about disasters without causing too much disruption? Time machines could be a force for good if used ethically, although that's probably wishful thinking.

You've all seen 'Back to the Future', right? The first thing someone's gonna change is making sure their dad ends up with their mom. Or maybe just mess with their worst enemy by dating their mom instead... Haha, but seriously. Time machines would be the end of the world as we know it. Everything we know could change in an instant!

lol everyone's thinking too small. I'd go back and convince my parents to invest in Apple and become a billionaire overnight. But chances are someone else's gonna mess it up and I'll end up never being born.

idk bout you guys but I'd just wanna meet my ancestors, see where I came from. That'd be so cool. But yeah, probs chaos would happen cuz people can't help messing with stuff.

Imagine the unintended consequences tho. Even small changes could snowball into huge ones,totally altering the present. It's that whole butterfly effect thing. We'd need strict rules and some kind of time police to stop people doing dumb stuff.

History nerd here, and let's be real, someone's absolutely going to try to prevent some huge disaster, like stopping the Titanic from sinking or assassinations. But, changing big events could have crazy ripple effects. The whole of history might unravel. There'd have to be some kind of time regulation authority, right?

Bro, just think about the Doctor Who episodes! Time machines would be so epic but imagine the paradoxes. I bet the first major thing people would try to do is go back and win the lottery or save celebrities like Kurt Cobain or Tupac.
