I'm running a Roon end point using RoPieee OS[1] which is connected to my DAC and amplifier. This also allows me to do Airplay or drop any streams on it so I can listen to it either on headphones or speakers connected.
Perhaps approaching from the point of view of programming as a means to end might be helpful? If they have any hobbies or academic projects that could benefit from automation or using computers, that might be a good starting point?
For example, when I started studying engineering, it was great to see solutions of differential equations and ways to solve them on computers. Others have suggested games which could be great if they enjoy gaming and want to know more behind the scenes. Basically my approach would be to find a problem or two and use programming to show that computers can do wonderful things once we learn how to interact with them in various ways.
"Logicomix: An epic search for truth" [1] is a graphic novel that chronicles the life of Bertrand Russell (logician and philosopher) and his interactions with legendary thinkers like Gottlob Frege, David Hilbert, and Kurt Gödel. I really enjoyed this. It was fun and highly educational.
