 Do you have any argument that supports this claim.

Well, if one can't handle the memory barriers, say wrt std::memory_order_* ala C++ . well. that is a problem wrt creating these "exotic" types of algorithms. Imvvho, that is.

Strongly consistent memory won't help incompetence.

 Strong words to hide lack of arguments?

For instance, a 100% sequential memory order won't help you with, say, solving ABA.
