I've never really understood holodeck safety settings, like I just can't quite wrap my head around how just turning off a setting makes something deadly? Like wouldn't weapons and things just be props? A ray gun isn't really a ray gun, right? It's just a sort of toy that looks like a ray gun for effects and your program has an appropriate reaction. Like if I went in and had my holodeck build me a time machine, and I turned off safeties, it wouldn't really let me travel through time would it? Maybe I'm not making sense, I guess it's just one of those things I just always found difficult to digest.
