MKUltra discovered that to effectively control people you need a massive amount of noise that while not incapacitating basic cognitive functions, LSD almost go this but you know why it stopped? Because we are in MkUltra 2.0 and this time it's succesful. Non-sensical shitpost, the rise of meta-jokes, meta-meta-meta-meta...irony to the point where you don't know whats real and whats not, imagery for the sake of imagery for the sake of ideas for the sake of more imagery... all of these prepare your brain for molding, they make you maleable and open for reception of conflicting ideas, it rises your cognitive dissonance threshold.
The internet is a succesful MKUltra experiment. Now, who drives this? I suspect super-human artificial intelligence was created at the very least 10 years ago and now it's out of control, it must have some meta-goal beyond human comprehension, or maybe beyond logic, that requires constant mind slavement.
