No, I mean hardware is genuinely progressing. Software is going in circles. It's a culture thing. Legacy code should mean "battle tested code" not "boring, let's replace it!" We are so busy replacing perfectly working code with the latest fashion that we never advance.
Yeah - and I mean that its not being driven by the hardware folks, but in fact is a cultural phenomenon derived from the academia world and industrial world having different gears.
Yes, hardware is progressing (though we've reached a few limits) at an amazing pace - and we've pushed technology into quite a lot of cracks and crevices in the last 40 years (at least, thats as long as I've been in the computer scene) .. but what I observe is that, every 3 - 6 years, there are cycles of entropy and creation which are a result of the endless churn of 1. Industry -> 2. Academia -> GOTO 1.
Today's Rubyist is tomorrow's Cobol'er. It goes on and on, and this is - in my opinion - a people thing. Not a hardware thing.
