Very good point!
@arnandegans @tb As Yoda said: "Always in motion, the future is"
It's possible for the future to already exist without precluding free-will, if it exists in a state of non-deterministic uncertainty.
@tb entropy is a bitch though. Every decision we make has the potential to radically change the future, just not in any way that we can reasonably predict or plan for.
although most time travel models don't allow for linear time, so if you went back, you couldn't get back to the same future again anyway.
@tb It's mostly a hindsight is 20/20 thing.
It's a lot easier to retroactively assess critical pivots once they've already been demonstrated as such.
Although at the same time, one has to be certain it isn't just a single emergent manifestation of a general probability attaining realization.
#MultipleDiscovery and #SimultaneousInvention are two examples of such a thing where addressing any single instance would do all of nothing.
@tb Excuse me, but this meme is nonsense.
There is no point doing small things in the present, if you don't know they will be successful.
if you travel back in time you know exactly what small things to do to be successful.
So, this meme is just an instruction for chaos.
@tb Of course, in the former, the person has the benefit of hindsight and knows how things played-out. So they know what to change, and why.
It's a bit tougher without all that information.
@tb
That will not be a change.
You can change something you have. It's easy to change the present while you are in the past because you already know what led to this situation and what has to be changed. But even in that case, the changes may not conform to your expectations.
You don’t have a future yet so you cannot change it. But you can create it. Probably.
Story Time! I used to own a quaint little bookstore downtown. Loved it. Over time I became friends with a homeless guy who was nice, not on drugs, and didn't mind watching the store for me now and then. He never stole anything and I always kicked him a few bucks for his help. So the one night I'm locking up and it's POURING outside. Just coming down like it's personal. I see the look on his face and realize he's gotta go somewhere and sleep in that, and that sucks. /1
@tb I think a big part of the past-changing fear comes from two things:
-butterfly-effect style changes are unpredictable, which is true of both the present and time travel
-Completely changing the present via time travel is seen as a loss no matter what, whereas completely changing the future via present action is judged by the merit of the change.
@tb there are things once revealed that will give an entire game away. A person from the future wouldn't necessarily understand how such a ubiquitous set of knowns is so lacking in the past. Tell the wrong people and you're the most dangerous person on the planet.
One drop of water on acid is dangerous, but one drop of acid on water is boring.
