All of the discussions about instruction sets and "mine is better than yours" or "anyone else could do better in a small amount of time" are useless considering

All of the discussions about instruction sets and "mine is better than yours" or "anyone else could do better in a small amount of time" are useless considering those arguments, if true, haven't actually resulted in any free ISA being available broadly, embraced broadly and hardware implementing that ISA being available. It doesn't matter how great something else could be in theory if it doesn't exist or doesn't meet the same scale and mindshare (or adoption).
