TL;DR: the parent doesn't know what they are talking about and for some reason is burnt over OpenCL which is a horrible ""standard"" (Khronos extension over C and C++, not actual C++ support, in the C++ ISO standard

Intel and AMD voted to add GPU support to the C++ and Fortran ISO standards. Are you implying that they did a bad job and added the wrong GPU support to ISO C++? Or maybe that Intel and AMD don't care about C++, and either added GPU su

NVIDIA, Intel and AMD sit on the ISO C++ and ISO Fortran standard committees. They voted GPU support into the C++ 2017 and Fortran 2018 ISO standards. While NVIDIA implemented this YEARS ago, almost 5 years after these ISO standards were vo

What's rust support for structured concurrency ? C++ appears to be going to use it as its "main"/"most fundamental" asynchronous algorithms model: http://www.open-std.org/jtc1/sc22/wg2

Sure: TBAA, access to invalid union field (in C++), etc. Many of them are impossible in theory to check, and many are impossible to efficiently check in practice.

The implementation of the Rust abstract machine - miri - stops execution of Rust programs when they exhibit undefined behavior. C, C++, etc. don't even have implementations of their abstract machines. They don't have one existing
