Action potential, attenuation, and language learning

You are not a machine, you probably don't talk to any machines, and if you do maybe they are in disguise in preparation for the upcoming take over so I, for one, welcome our new machine overlords...

Okay seriously, I wanted to talk a bit about language learning because this is a language blog and now I get to mix that with a bit of biology.  I couldn't be happier if I was in a hot tub full of Chihuahuas or as I like to thinks of it, vicious, wet, bitey, bitty things....of death.

In action potential is the rapid change that happens as a result of stimuli, but it cannot be just any old stimuli. The stimuli have to surpass a threshold, i.e. be big enough.  So I want to point out that mistakes are the stimuli of language learning and not acing a French II vocabulary quiz, or when I tried to be suave and deboner and impress the French girl beside me by saying "Je ne parle pas français" and she was like, "What did you just say?" So I proved my point but not the point I wanted to make. Now if I had followed that comment up with asking for her help it could have been repeating my mistakes and coming up with new ones before sunrise but with better facial hair. Or not as the case may be. 

So mistakes are necessary but they also have to be made a certain number of times. Borrowing from the word of martial arts, we could sit down and I could show you how to perform an Ippon Seoinage throw in 5 minutes. You could practice a few times and if you felt confident in doing it then you are wrong. If you went on the mat to practice you would quickly find out that it is really hard to move your body, move your opponent and time the whole thing correctly. If you are thinking about how to do the throw you aren't going to be able to do it. 

Likewise, if I showed you the conjugation chart for vir in Portuguese there is no way you would be fluent. You have to understand how the word is used, all the chart says is the subject, verb, and time sense should match and any computer can do that. What the computer cannot due yet is understand the meaning once the rules have been broken. For example if I said, "I are going to the store, you too having wanted to come" it is obvious that I have broken all sorts of English grammar rules, but the meaning is not obscured completely. So the question is does the above sentence represent fluency in English?
