(I ~think Go also always had facilities for sharing memory as well. Don't remember.) The issue appears to be: - "It's impossible to build real systems" according to pure conceptual CS models, - or, our conceptual models are not sufficiently strong and expressive, and fall short bridging the gap between symbolic and physical realm, and these gaps manifest in code. - or that it's impossible to practically realize more complex conceptual models, and that even if possible, they would not be accessible to the general programming community. - or we're building on poor legacy foundations which will dog us until we finally rethink approaches from ground up. (Possibly those ORs are all ANDs.)
