Then again CUDA is pretty accessible language to program SIMD machines. I am bit sceptic if most people would recognise subjectively well-done SIMD language (lets say from correctness and performance standpoint). The programming model for SIMD is inherently parallel with exceptions for sequential code, which is pretty much the exact opposite of the programming you do on the CPU side. I'd somehow imagine most people would not find that modern at all, or alternatively, it would not be the language with "product market fit" since it's less likely to catch on. AMD or Intel may have a "better" language in some sense, but it seems most people prefer familiarity with what they already know.
