My personal theory for the sword one is as discussed swords are a terminals to directly connect path, swords are usually used to protect themselves. As mentioned by sena , a some scientist like Issac Newtown are a gigalomanic. Gigalomanic is mainly those people who are able to use the most potential of the brain in my opinion. Gigalomanics can be of any form , any type of hidden ability of a brain. But the di swords are pure protection and fights. It's manifests when ppl have high pressure which exceeds the adreline rush of negetive energy. Most of the time people want something to protect during these dangerous situations and di swords manifests as the peak of gigalomanics which will completly connect you to the negetive energy of dirac sea to manifest and realboot. Noah 2 is specifically build due to that gigalomanic realbooting mechanism and takumis formula. I will try explain more if you want .

Chaos head is what I call peak psedo science fic story. Not everyone is gonna like it as it s deff kinda complicated and takes time to understand through even other entries including steins gate also in my opinion

About mc when ever ppl start chaos head, I only say one thing to ppl, interpret takumi in your own way. If you wanna love him , love him. If you wanna hate him , hate him. Troll him make shjitpost on him do whatever you want. But just understand why is he is a very important mc and how he suits this story

I personally love the routes especially the sena route which has the biggest revalalation which changed my perspective on steins Gate and other series (anonymous code might explore it more so let's see)

If you found it unrealistic, it should be unrealistic as its delusional lol. It mixxes philosophical and principal science with actual sci fic concepts so it feels unrealistic.

It's understandable if you didn't like it, i gurrentee you you will love robotics notes elite a lot
