summary

C++ claims to be flexible abstraction and efficient by definition while its specification balloons to about 1800 pages, with std::pair implementation swelling to ~502 lines. Tooling and libraries remain strong, yet integer overflow stays undefined and threading primitives encourage ad hoc parallelism so Photoshop grows from ~100 to ~2000 threads. A working Photoshop port compiles ~30 million lines of C++ to wasm/asm and runs in browsers, proving feasibility while exposing poor C++ networking and GPU portability gaps.
