There are many models for time travel. Sometimes, travelling in time creates a separate timeline, this is neat, because it avoids paradoxical logic. But a model where there is only one timeline, and if you change something, everything that comes after ceases to exist, has some interesting dilemmas.
The 20th century was marked with war and genocide. Historians would say that this is the result of many complex societal factors and events, but for the sake of argument, let's say you could go back in time and prevent it. You figure out a set of action that will create world peace and today we'd be living in an objectively better society.
Only problem is that we'd all be dead too.
Everything that happened in the 20th century has shaped the lives of our ancestors. They'd have been raised very differently. How do we know our parents would have met if it didn't happen?
And the conception of a child is a very random event. If your grandparents had sex on a different day, then your parents would be very different people. Would they have found one another?
Without time travel, it is rather nonsensical to think of the people who weren't born. Only weird fringe people do that. Most would agree that wearing a condom doesn't mean you're killing a child by not making it.
But with time travel, it's different, because the people already exist, and maybe you'll make society objectively better, but you'll also kill everyone they already exists. You'll also kill yourself by the way.
It's a kind of trolley problem. You take action for a better outcome, but you are responsible for the negative consequences of it, or you do nothing, accept that reality is what it is. Whether an omnicide is better than a genocide.
When the infodump turns into an infobomb and then an infonuke and now I'm on the CIA's watchlist or something what the hell I just wanted to know some stuff for autism purposes
Surely completely deaf beings would think in sign language, right? What about partially deaf beings? Assuming thinking in sign language is a thing, how much signing does it take to start thinking in it? Does it even happen to non-deaf beings who learn it but don't rely on it to communicate on a daily basis?
Also you know how when you know multiple languages you might code-switch between them in your thoughts. Is code-switching between spoken language and sign language... a thing? Surely code-switching between different sign languages would be a thing though (assuming again that thinking in sign language is a thing).
Everything that lives is designed to parkour We are perpetually trapped in a civilization of jumps and falls Is this a curse, or some kind of punishment? I often think about the Parkour Champion who blessed us with this cryptic enigma And wonder when we'll defeat him in a Parkour Battle
