I'm new here, an amateur physics buff with some degree of mathematical sophistication. I've read and watched a lot of Susskind's work, and I am fascinated by the as-yet undiscovered (or uninvented???) theory of quantum gravity, black holes fascinate me, as does the small but non-zero value of the inflaton fields potential, and, to a lesser extent the properties of dark matter. For a lark, I'll hypothesize that dark matter has many charges, and has a rich structure, but only interacts with standard model matter via gravity, so that I can further hypothesize that there is life within the dark matter structures, horrible, Lovecraftian life! Moohahaha!
