I look at it this way:
Your brain is your computer. You are born with a specific configuration and that is what you have to work with. Learning is the same as storing info on your hard drive. It doesnt make you smarter , it just makes you have quicker access to information. Adding info to your pc doesnt make it a better machine. It wont be a better machine than you bought simply because you have x amount of gigs of info stored. It will be just more useful to you.
Same with the brain. Its not a better brain after storing things in it, just more useful to you when you need to access info.
Now software is a different thing. Installing specific software on your computer will determine how it runs, how well it runs and how you can use the info. Our software is all installed as children with limited capacity to upgrade as we are older. The first 7 years or so determines our software environment in out minds. After that its storage and manipulation.

Much of what you learn in school is temporary.
What you learn from life experiences is permanent. The process of weeding out useless info is ongoing and we defrag and clean up on a nightly basis.
Does this make sense to anyone else but me?
