Digital natives do not exist in numbers you think. Fewer than 1 percent of entering freshmen have ever edited a wiki:

EDIT: Totally misremembered, its more like 17 percent.

If you want an alternative metric, something like 1 in 3 entering freshmen don't know what the BCC feature does in email. We know that pretty much everyone uses email daily (despite what they tell parents and teachers), so it cannot be that immersion alone leads to proficiency, or that proficiency cannot be learned as an adult.
If you want to rate candidates by skill, by all means do so, just don't go the extra discriminatory step of saying old people by definition cannot pass your measurement, and that young people by definition do.
