pic related. two young studs, with iq's both well above 170. I would assume not any slang would be in the conversation. A book with tesla and edison having a private conversation would be one the most read/published pieces of art in collaboration. Just an open dialogue of these two, Holy shit man, the conversations these two had were PEAK HUMANITY. Easily in the top 50 most provocative, propelling conversations that shaped our current reality that we live in. Imagine how concise the conversation would have been. No stuttering. I know edison had a temper problem, so he probably spoke as if he wanted to punch tesla in the mouth, except in a sophisticated manner.
