Yes, but these things happen. In the 1950s-1970s many young people (at least in America) were obsessed with cars and as soon as they could afford it, they got a car and spent huge amounts of time improving them, rebuilding their engines, etc. When I was a teenager in the 1980s, cars weren't really things to get excited about, but rack-based stereo systems were. We spent hours reading about which turntable, speakers, and amplifier to buy and were constantly in the process of improving their system. By the late 1990s, that had become passe and people either had non-modular stereos or just listened to music on their Walkman (and then iPod, then phone) and didn't have a stereo system at all.
