I just made the C64 <-> Pi 400 comparison to someone last week. It is completely analogous.
Pair that up with an arduino, and maybe wiring, and you can a have hardware interaction with a Linux desktop on the 400.
I just helped a young arduino user with reading an analog pot yesterday. There are still young people out there playing with hardware, and it is way easier today than it was for me in 1984.
Then go over and look at the people configuring and compiling custom versions of Marlin for their 3D printers.
Or the nerds designing flight computers for solid fuel model rockets.
