You are wrong here.  Emacs 23 added many CPU-intensive features, like
visual-line-mode.  Emacs 24 added bidirectional display, which makes
redisplay need roughly twice as much juice as Emacs 23 needed.  And
these are only two examples that pop up in my head after a 3-sec
thought; I'm sure there are more.

So it's not like we use up every additional CPU cycle the chips are
giving us, but we are certainly using significantly more than we did
10 years ago.
