Maybe by materializing right in front of them, you could aggro some that would otherwise be passive. But by the same token, the materialization could also scare some of the aggressive ones. I think it's more likely than not that you could get attacked by a hobo but I don't think it's overwhelmingly likely. And even if they want to attack you, you could always try to fight back or run away, which aren't great options but still.
If someone from centuries ago appeared today, I don't think they'd instantly be fucked over. I guess it depends where they spawn, but I could imagine them appearing in a city and everyone just being curious about them, not really aggressive. And if you know you're going to be time traveling, you should already be kind of prepared for the future anyway. You'd expect to be out of place when you arrive, so you'd probably think of some way to communicate that you're peaceful, and maybe some people might help you learn the language. I think also most people know about the idea of time travelers now too, so I think the people who see the time travelers materialize would be more empathetic and have an idea about what just happened. Basically, if you know someone is a time traveler and they didn't seem like they wanted to hurt you, you'd probably be a lot more inclined to help them out.
>>16224463About people innately wanting to learn, I kinda agree. I think that's the case. It's really hard to imagine that mankind stops trying to create and improve unless there some fucked up mutations or something occur. But the one thing that gives me some doubt is looking at the effect of technology today. People can learn whatever they want, but they spend their time on YouTube or typing thousands of characters of shitposts that nobody will ever read. It's insanity.
