Typo alert: not “t’Hooft” but “’t Hooft”.
Motl is … not exactly immune to charges of crackpottery himself.
Gosh, thanks, fixed it… I know I’m not the first to screw this up, but still...
Yes, Motl has to be handled with lot’s of care, though usually as far as physics goes I find him alright (unlike say climate change and a bunch of other stuff). His tone can be off-putting, but I see him still as a useful contrarian in some areas and generally an interesting case study of an extremely bright person with some strange opinions and a very… interesting personality (to put it mildly).
