Despite not being the best medium for music, I find cassettes to be a really impressive piece of technology particularly due to how easy it is to write content to them.
I like old tech too and in the 1990s I recorded a lot of audio stuff straight from the radio, but nowadays with USB everywhere I just would not use tapes anymore. I just find USB sticks so much more convenient. I kind of transitioned into the digital world only and while no transition is perfect, I feel that the trade-offs are in favour of digital only rather than audio.
Even listening to the radio is different, I'd just use mpv and record the stream into a local file, as-is. It is strange how new technology obsoletes old tech but I also don't want to go back anymore. Though old hardware is cool, I love old computers from the 1970s and 1980s. They are so much cooler than the modern computers, even though the modern computers beat them performance-wise with their eyes closed.
