Whenever I buy a console I'm super aware I have maybe 5 years of using it before I'm forced to upgrade to the next console. It's even worse with phones. I wonder how many of these devices (or realistically, new features existing devices) are held back on purpose to justify a new phone every year.

What is the current rate of technological advancement if we discount capitalism creating a culture where businesses don't put out their best product always, and innovation is not innovation for the sake of itself, or to make people's lives easier, but a tool used to beat out the other guy and keep making money off of people every year?
