Dunno about everybody else.  I did not

a) say that CPU's are fast nowadays,
b) say that it does not matter that Ruby is slow,
c) claim we should not care about Ruby's performance.

I specifically asked "does it matter?"  For me it doesn't (especially 
since 1.9 is there) but that does not mean that it doesn't for others. 
Hence the question.

Kirk has responded better than I could and I believe there is nothing 
more I could add to this.
