I don’t think this will be an issue at a school like Yale. It may be less techie than MIT, but there will still be plenty of students who have been writing code since they were like 10. I doubt you’ll come across anyone who has no idea what coding is.
Honestly, I don’t think it matters. They’re both great, and both have good reputations and a foothold in recruiting at large tech companies. MIT is stronger in this particular field, of course, but I don’t think it matters so much at the undergraduate level.
