Maybe it's already mentioned but in my opinion the dream sequence with Alice photographing the landscape at the end, which is about "everything is subjective" is a really hefty sequence.
The writer of that scene is in my opinion a fanatist.
MUST is a really strong word for the medium which should be able to transfer ones feelings, thoughts and emotions to another human beeing so that both "understand" each others words and expressions.
I must die.
I may die is wrong.
So, you are saying, mankind MUST find a medium like in a bork collective with a single alpha commanding the functionality of others brain? Have you really thought about ?
brain doesn't work like planning a city. even a caucasian brain has other regions activated than an asian when thinking about sex. That's the reason why the common buyable brain thought reading equipment is only ready for 5 languages.
That's a more horrifying vision you are painting than the nuclear bomb 80 years ago...
That's more than the vision "1984"
And who is in control of that medium?
a human beein? AI ?
Both are restricted in their accumulated nowadays knowledge
If you turn on that medium, there will be no future and everything mankind developed will be frozen at this stage.
No inventions anymore as each brain is controlled and restricted to this programmed mediums input and output
And how would you deliver the brain to brain message? radio frequency waves?
You know, that those manipulate a humans own frequencies and are able to freeze blood plates, right? That's what's called embolism and if areas of the brain aren't blood flooded, they die irreversible.
I know, I know.... Snowden told us about academic researches and their first steps .... It's completely wrong and I'm strictly against any kind of emollient in any kind of propaganda for this technologie.
For me, your message reads like: a bullet in your head is a must have
