That is only temporary. You need to know some of them at least, but you don't use them that much after a while. I rarely uses any of them now. In my opinion that is not a big thing so I don't understand your reluctance. Here you have a method that has been proven to work many times and can give you a very fluent life where you can enjoy talking with others, hold presentations, and stop thinking negatively about speech. For me it seems that many on this community uses more time to complain than working on a solution, which is very sad.
