Eh, again you're just saying "it's not real because..." whether or not you attach the word theory. It is a space with lots of possible parameters being explored and is not one set of parameters with predictions because all of the sets that have been explored so far are either broken or don't represent reality. That in itself does not mean it doesn't have merit. It's simply incomplete, but given its history it's fair to doubt that it ever will close the loop and have a final form that models our reality.

I'm not sure what you're disagreeing with tbh. If you look up the thread, my point is that the reason string theory is untestable is not simply that high energies are experimentally inaccessible. Rather, string theory doesn't make any definite predictions for those high energies either. It seems you agree with that?
