My problem with Moore's law or the other things that pass for Moore's
law is that it is intrinsically wasteful. Yes, it's great that every
year there is more speed, cheaper memory and disk capacity. Yeaa. But
should it be our aspiration to write such bloated and sloppy
applications that we need this horsepower just to keep the same apparent
performance?

One of the reasons I love (not just like, LOVE) Linux is because it
runs like a banshee on "old" HW that M$ has consigned to a landfill.
This to me is Great Virtue. Relying on Moore's law to keep things
running is Sloth and Vice.
