As an industry we need to worry about this more. I get that in business, if you can be less efficient in order to put out more features faster, your dps[0] is higher. But as both a programmer and an end user, I care deeply about efficiency. Bad enough when just one application is sucking up resources unnecessarily, but now it's nearly every application, up to and including the OS itself if you are lucky enough to be a Microsoft customer.
The hardware I have sitting on my desk is vastly more powerful that what I was rocking 10-20 years ago, but the user experience seems about the same. No new features have really revolutionized how I use the computer, so from my perspective all we have done is make everything slower in lockstep with hardware advances.
