Earlier quoted context omitted.

When thinking about this one, I always wonder if it even matters.. playing both "Yes" and "No" scenarios doesn't really offer any insight for me. Maybe it's a degree of nihilism but it makes me not get overwhelmed.

A simulation has a nonzero chance of having exploits, and it's debatable whether it is in our best interest to discover them.

What's an "exploit"? Is electricity an exploit of that weird phenomenon where a balloon sticks to a wall sometimes?

Only tangentially related, but the lovely (quite) short story "I don't know, Timmy, being God is a big responsibility" is fantastic and kind of hits on simulating worlds, in a sense: https://qntm.org/responsibility

I’m not sure I really know how to handle this. Do I just read the latest version linked at the top of the page? Or is the one offered by this like somehow more canonical or something? I’m not sure I’ve ever been faced with different versions of a fiction before. Just textbooks.

I really love thought pieces like this if you refrain from poking holes in the logic or physics. I love the idea of a multiverse where they’re all actually just identical so it’s mostly moot.

Sometimes I wonder what it’d be like to live in simulated universe.

You say that as if you aren't. What proof do you have either way?

why does it matter?

If we are, we're in a sandbox that cant be escaped. live your best life and get on with it

If we aren't Live your best life and get on with it.

I've never seen the point of the question.

There is an excellent hard science fiction book called permutation city that very related to this topic…it made me feel like i was in a dream when i read this post’s title

I finished that book yesterday. I had exactly the same reaction.

>written entirely in GLSL fragment shaders What's the language for that? (The music is pretty cliche. Maybe it was written by AI)

The music is "Adagio in D Minor", and probably cliche more because it's been used so much rather than because it was cliche when written. It was originally composed by John Murphy for the 2007 film Sunshine.

Not sure if that's actually your question, but GLSL is the language https://en.m.wikipedia.org/wiki/OpenGL_Shading_Language
