Unfortunately modern computing trends make "reuse" pretty difficult too, what with software bloat and increasing layers of abstraction ensuring that everything becomes slower and slower over time, possibly just so that you will buy new hardware. Wastefulness in computing is a decade+ long epidemic.

Not that long ago users here were talking about 3 seconds to launch a word processor being "pretty good", which is an insane statement to make when you're taking about multicore processors that can execute multiple instructions per cycle and run at 3 billion cycles per second. Modern software is the computing equivalent of burning rainforests to roast marshmallows.
