The official Subreddit for the Isaac Arthur YouTube channel. This Sub focuses on discussing his videos and exploring concepts in science with an emphasis on futurism, space exploration, along with a healthy dose of science fiction. I mean the type of VR that is directly hooked up to your brain instead of your external senses and is more or less indistinguishable from reality (is there a proper term for it?). Do we have any idea how to do it, or is it purely in the realm of speculation at this stage?
