@Lex Fridman: Your title misuses the word theory. A theory is the highest form of scientific explanation (ie: the theory of evolution). <br>A lab leak origin for the SARS CoV-2 virus is un tested and un confirmed speculation - nowhere near a theory. <br>It (lab leak) could be demonstrated to be a correct explanation, then it would be a fact. <br>Words have meaning and using words outside their meaning leads to more, not less, confusion.<br>Good on you for talking about this anyway.
