Well, yeah, there are a lot of people who neglect friends and family for some kind of obsession - some write books, paint, create music, write software that outlives them to some degree or at least improves or inspires the lives of many other people. This guy spent his limited free time (and that of his family) building his dream stereo system, finished it when he was about to turn 80 and didn't have a lot of time left to enjoy it, and after his death his life's work was sold off bit by bit for far less than he invested in it (financially, not even mentioning the countless hours). So, to me, it's a cautionary tale to be wise about how to spend your time...
