A lot depends on whether seniors ever used computers during their work careers. I’ve had a personal computer since 1983. There are some seniors with much experience and knowledge of computers.
some of us even work in IT
I am now officially a Senior Citizen. My first exposure was to an IBM mainframe while I was in high school and we used Fortran. We had mainframes in college. In grad school our department got a PDP system and we worked together to program some plotters to make figures for papers and our dissertations. Our family has always had computers and used them for more than games. I can program in C, C++, Fortran, R, and Python. I use the the language that best suits the problem at hand. These days I use mostly R and Python. In most instances the problem is between the keyboard and the chair .
Surprisingly this thing has come full circle and there are many many young adults now who know virtually nothing about computers and they are working or attempting to work in a professional environment where a computer is central tool in their job performance. Many companies these days just "assume" a young person has computer skills when a ever growing number don't. The days of needing some knowledge of how a computer operates and it's basic parts in order to use it are long gone. Young people just expect the computer to work and don't have the first clue of what to do if it doesn't.
