Other than those who profit monetarily from it, no one I know wants the PC to stick around longer than it has to.
Motor vehicles have their demise built in, but they genuinely wear out.
PCs sit there in the confines of a warm room and quickly waste away, purely as the result of premeditated market dynamics. Dell Computer PC whose disk drive has been full for more than two years. Windows 98 remains a horrid piece of software. Shame on me for not moving to Linux or the Mac, but I have neither the time nor the interest in switching computing platforms. Like everyone else, I'm too busy, and there's little upside to adopting a new PC platform as my next hobby.
