His old university lectures on Youtube were pretty good, but he has always had this habit of mixing in things he believes to be true and stating them in a way that made them seem scientifically sound, but they were more speculation than anything else.

And you can't tell apart the good information from the bad, which makes him quite problematic.

Also nowadays he has completely lost his way and only rarely says something sensible.

It's best to either avoid him or to just have fun watching him overextending and misapplying ideas :)
