Tadge is allowed to be interested in whatever he likes, but on the ground, people see a Bitcoin Dev talking about quantum and they don't read this as some autistic little hobby horse lark. They read the situation as immediate and dire, and they want to know how unsafe they are. So, ironically, Tadge even opening his mouth in a very public fashion is achieving the exact opposite outcome that he is ostensibly trying to avoid.
