I have to disagree with you there. I teach computer courses at 2 local colleges in both the Continuing Ed and Corporate divisions and older people make up the bulk of my classes. They know that to be valuable in the workplace they need to hone their computer skills.
You are dealing with people who are proactively trying to learn. I’m talking about people who just get hired. College students and the like are already very literate in that area. Most retired and older workers seem more timid in that area. Some of it is due to gaming I think. Gamers tend to be more computer-literate.
