@Asimong I think your points actually help the metaphor. The Red World is emotional! It’s dangerous, exciting, hot. The Blue World is peaceful in the control, safety and familiarity but this can lead one to become depressed. You’ve also hit on an inspiration from my favourite movie. In The Matrix, the hero is presented with an option - take the blue pill and stay in the comfortable reality or take the red and discover a dangerous truth. Typical adventure stories feature a magical, mystical world the hero enters - the Red World. The Matrix with it’s Gnostic influence flips this to say that the underworld is more real and maybe it is - at least I believe it is more important.
You can see that this goes beyond brain hemispheres. I recall @laurenw speaking about the design of spaces in the research meeting. She said something like “how do we make them more right hemisphere…for lack of a better term”. This is where the metaphor is handy. Typical conference are Blue World and we want something Red World. More than a way of thinking -the environment and our relationship with it.
Fire vs screen is just a starting point. What about subjective/objective dualism, heart and mind, materialism vs relationality. I encourage you to continue playing with dichotomies and see how they might fit the framework.
