Wow. They picked a theme and they sticked with it!
Matrix to me seems like the odd one out. All the others have human names and then there's the mathematical concept. I'm not a fan. It's like having
Emma,
Emile,
Mikhail, and Anarchism. I can see why but still one is not like the others xD Also, importantly one is just straight up the name of the theme itself and so in a way encompasses the others.
