I use sign language myself everyday.

Sign language is way more than just gesturing. I did not see read that link from the above post, regardless, gestures are fundamentally a semiotic expression of meaning with the body rather than speech.

Like sounds, one can create a basic Piercian sign, and build onto that sign.

I believe that sign language has the unfortunate implication of being composed exclusively of gesturing. The word “sign” is confusing as well, especially when “sign” signifies (pun intended) a set of commonly understood meanings in linguistics. Body language, gestures, manual expressions all are just parts that come together and become more than the total of sum parts.

I see spoken and sign languages as two different tools that can do similar job with different features and weaknesses. Like python vs go vs JavaScript.
