Does anyone really care about Luboš Motl's ramblings any more? He seems to be the prime example of a smart person who gets too attached to his ideas and beliefs so he just digs deeper.
Yes for string theory and all related topics, with the exception of interpretation of quantum mechanics. In which his adoption of the Copenhagen interpretation is very reasonable as praxis, but doesn't make sense to me as metaphysics.
He’ll be the last string theorist when everyone else finally understood it was a dead end, thereby proving my point.
