Humans do not utilize the full potential of their mind. What percentage we use is moot, we are capable of much more than what we do now. Ignoring the movie's meaning over a percentage is semantics. Look at the bigger picture they were trying to paint. Clearly they had to illustrate it through some medium that it could be understood by the population.
The chemical Lucy was foreshadowing to is, well, Lucy. Lucy is the name for LSD. LSD has the ability to give humans supernatural abilities, I have experienced momentary levitation with the help of LSD myself.
LSD evolves your mind by increasing your sensory input. Give the right amount to the right user and they would gain access to supernatural abilities. I believe I can take flight given access to a thumbprint of LSD (a thousand hits), considering I partially levitated with only 3 hits or so.
So yes, open your mind, expand your potential and evolve. Lucy awaits you.
Funny you mention that because just the other day I was talking to a friend about how a couple of times in highschool when I was on LSD I was predicting things before they happened and telling people what they were thinking and freaking people out with these types of abilities. Another time I was predicting things in the world that were gonna happen and making my friend break down literally into tears when they were coming true because he didn't know how I could come up with such predictions on things and I had explained that when I was tripping out on the LSD it was like my mind was open to everything and I could just think of things and the answers would just come to me
I also had a bunch of people freaked out at a party once when I predicted exactly when the party would end and the reason why the party would break up and the people who would influence the ending of the party and the reasoning why they were arguing which some people just couldn't believe. Needless to say I had quite the occult following when it came to taking hallucinogens because everyone wanted to trip out with me and just listen to what I had to say and what I was thinking while I was hallucinating lol anyways found this topic quite interesting and figured I would share my story with people
Cheers and Have a great day everyone
