The basic answer I get when asking this is 'because hardware has changed' which is obvious but avoids the question. Sometimes someone will bring up vector instructions are supported in rust but for a large portion of programming you don't want to vectorize (seriously measure what you think you need to vectorize). Ideally a compiler could compile $lang to word at a time aka SWAR if needed.
