Oh fuck. Oh bloody fuck.
Pray tell, what have you studied to have such a... vision of human intelligence and capabilities? On what basis can you consider that the human brain is a universal thinking machine when noone has any other example of intelligence to which we can compare said human brain and thought processes?
You are like a chemist who has studied his entire life the properties of helium, who has never gotten any hint of any other atom in any way and who claims that if we can manufacture that fabled hydrogen, it will behave just like helium. Then goes on to explain how it will allow us to build a better-performing zeppelin without any problem.
Not only you have no idea what you're talking about, but you do not even realize you do not have any idea of it. And this, people, is why one of the first and most important realizations of higher learning is how much we have no clue. And how much we probably don't know we don't know.
Fuck, we have no fucking clue what 95 percent of the universe is made of - except that it isn't matter of any kind we ever observed, or matter, actually - but you claim we can easily understand a completely alien intelligence. That level of arrogance is EXACTLY what terrifies me.
