Obviously there's a balance to be struck. There are certainly schools and teachers that teach arithmetic poorly, and there's a practical limit to the amount of hours spent doing equations before it becomes tedious busywork.
But I still think it's important that kids are taught how to do arithmetic by hand. And part of that will involve repetition, both to help reinforce and practice skills, and so educators can more accurately gauge a student's ability. You can't just bypass the need to sit down and do the work, even if the exact amount of work necessary is debatable.
