if you were given the opportunity...you can have the brain function to understand literally anything...quantum mechanics, time travel, music theory, etc. but you have to surrender the ability to express/demonstrate/convey that knowledge, would you take that deal? And when i say you are unable to convey or demonstrate i mean, for example, you know how a time machine works but you don't have the ability to build it yourself nor do you have the ability to explain to someone else how to build it or to draw up schematics on how to build it. And i'd say like okay yeah you can have some journal with all your equations and stuff but they are so high level that not even the most brilliant scientists or mathematicians can decipher it at all. Oh and for the sake of this hypothetical, possessing this knowledge will not in and of itself kill you, its not like that the 1996 John Travolta movie Phenomenon (SPOILER ALERT SORT OF EVEN THOUGH THAT MOVIE IS OVER A QUARTER CENTURY YEAR OLD SO EFF YOU)where like he suddenly is wicked smaht but its because he's got some kind of tumor that drastically shortens his life. No no, in this scenario you will continue to live out your life just as you would have before you knew exactly how everything in the universe works. I suppose maybe it could drive you mad with frustration that you like, understand how to do nuclear fusion and could provide free electricity for the entire world forever but you don't have the ability to build that machine or show someone else how to build it. That might drive me crazy.
