"This ×3 multiplier contains roughly 9000 transistors, a bit more than an entire Z80 microprocessor (1976). Keep in mind that the ×3 multiplier is a small part of the floating-point multiplier, which is part of the floating-point unit in the Pentium. Thus, this small piece of a feature is more complicated than an entire microprocessor from 17 years earlier, illustrating the incredible growth in processor complexity."

That's the pace of performance growth that lead software to become bloated today; next year's performance improvements would cover up most of the sins of failure to think critically about algorithms and data flow context / locality.

Today (as far as I've read) we're at the practical limit for what's reasonable to do with silicon semiconductor technology and our present understanding of physics. The pendulum needs to swing the other direction; it's time for computers to work smarter not harder.
