This guy is a real-life Ozymandias

From here (emphasis are mine)

"As a visiting professor he’s taught at several universities in Canada, the U.S. and Denmark. What’s remarkable is each appointment was for a different discipline: Visiting Professor of Mathematics, of Nonlinear Studies, of Chemical Engineering, of Theoretical Physics, and of Complexity Research. Currently teaching Chaos Theory and Brain Theory at the University of Tübingen, he also collaborates with ATOMOSYD, a French research group studying Topological Analysis and Modeling of Dynamical Systems."

So I think his words carry some weight.

That part of CERN delibrately creating black holes is complete bunk, though.

There will be many reasons humanity will die-off, a black hole won't be one of them.

I suppose he was doing it out of principle (or at least, he thinks he is). That article I linked had this snippet:

"In physics you’ve got to be a physicist, especially a pre-eminent one, if you want to challenge CERN, which of course is loaded with them, including Nobel Laureates. It’s not just snobbery, but it’s more or less the club rules today. If they had been applied to Albert Einstein when he was drudging as a clerk at the Swiss Patent Office, he would have dwelt in obscurity. Actually as it happens, Einstein’s logic informs much of Rössler’s thinking on black holes."

Then later on, this bring up this issue again. Feels like Dr. Otto is using this as an argument to prove his point against 7000+ of the best and brightests physicists.
