The impression I've formed is that physicists have a pretty good idea what's pretty reliable (the standard model) and what's still completely speculative (string theory) but at some point the popular science pipeline communicating the difference to intelligent scientifically literate non-physicists broke down, and so I became broadly cynical about non-experimentally-verified physics in general, when if I'd had more information, I'd have been able to make much more accurate predictions about which were very likely, and which were basically just guesses.
