It's literally why you're typing in a User.. lmao, I'm not the one internalizing here.
Hacked: User2 doesn't get hacked. If it did, it'd likely be game over. Characters get "hacked" and their "wires" get tangled.
Meta: I get where you're coming from, but you're confusing your theories for facts instead of just theories. Just because it could be symbolizing or implying something, it doesn't mean that's all it is doing or if it's actually doing that at all when it could just be trying to make you think that, or it's simply the easiest way to comprehend the idea of what's actually going on. Simply ignoring the possibility that supernatural stuff is actually going on, is just holding you back. I mean, I'm not saying you're wrong, but it's always better to have an open mind.
Akira: I agree with this. See, the actual plot twist seems to be that Sensei doesn't really matter as much as we think. He's not the only one seeing things. He's not that unique. Ami, Maya, Sara, and Sana, plus Nodoka, and likely others are going through things in the background that Sensei has no idea about, nor do we yet. They black out, see beings, and in Sana's case is getting her lust screwed with. In Sara's case, she may actually be a being. In other words, what Sensei perceives likely doesn't even matter that much. Perception isn't actually reality, it's just how one sees it. Him seeing a computer god or someone telling him about a god that is science incarnate in a dream, could just be his mind trying to understand this reality and the beings that are screwing with it. Same with HOPE, Nozomu, and the Mayas etc. Tbh, based off how the gods have different names for the girls and the girls we know have alliteration names, it's likely that we don't even know their actual names, nor does Sensei. Akira Arakawa may not even be his actual name, and Sekai (The World) itself, may be simply a fabrication. Akira having a brother named Nozomu who's name means Hope seems hard to believe as well.
Anyway, things are starting to get a little "too real", and my connection (heh) is shit at the moment, so let's just agree to disagree.
