Well, I'm an introvert, and that's not the same thing as SA. If I'm "cured" from SA, I'll still be an introvert. I'll just be able to do stuff that I need to do, which coincidentally involve people: school, work, shopping, etc.
I'll never be a social person, because I just don't get any pleasure from being with people. At best, it bores me. At worst, it gives me a panic attack.
Edit: I forgot to say, I think that knowledge would actually leave you less motivated to cure yourself, because you're not missing out on anything emotionally satisfying.
