  C++ ABI issues seem to be in this paradoxical situation where the language standard powerbrokers simultaneously feel that

  a. Having a real binary compatibility story is beneath C++, but

  b. The accidental ABI compatibility that exists today is too widely adopted to break.

  Am I wrong in thinking that this mild form of schizophrenia ( no official ABI but dont break the ABI) is part of the reason why we now live in a world where all applications talk to each-other through sockets, incurring huge overheads?

  The reference is a 1h YouTube video.

  Discussion of whether the next (or any future) c++ release should break abi compatibility.
