My father-in-law got a Master's Degree in Computer Science 30 years ago. IIRC, it was heavy in C programming and involved typical CS fare like algorithms, pointers, sorting, data structures, etc. He was a high school math teacher at the time (he's now retired). He took the classes mostly because he enjoyed learning.

I did ok during the Dos/Windows 95 era, but as time went on, he seemed less and less able to solve his own computer problems. He can't even Google a problem effectively (or even remember to try to Google his problem).

Most recently, I had to hold his hand while he bought a new computer at Best Buy and then further hold his hand as he went through, step by step, the Windows 11 installation/first time start up process.
