If you're saying that at one point in history, a given cohort of new CS students had never seen or touched a computer, I have my doubts, but it depends on how you define CS program. Before computer science was a formalized education stream, it had a variety of other names like "Business Computing" or something related to information technology, but you'd have to go pretty far back imo before you find a whole classroom of entrants into such a program that had never seen or touched a computer. By the time it was called CS, I do find it a bit of a reach that you'd find less than say 10% of students opting into taking it without that low bar being passed.

Likewise the biology example seems strange; sure maybe people haven't used a microscope specifically (unlikely imo), but they very likely have used any number of other implements and taken at least one secondary school biology course
