Eh, I think that's just due to selection bias. We're at a point where computers are such an integral part of life that the only people who do not know how to operate them are people who chose not to keep up with the times.

I have plenty of older patients who did not grow up with computers, but learned how to operate them later in life because they recognized their importance. They tend to retain much better cognitive function later in life than those who checked out of having new experiences a long time ago.

On the opposite side, I have plenty of younger patients who grew up with computers and are definitely not the sharpest tool in the shed.
