This is just hubris.
A worm has the same number of protein coding genes as us. Obviously the 'non-functinal' DNA is doing something important, we just haven't worked it out yet.
I would be very hesitant to criticize an evolutionary construct that has developed on a billion year timescale.
Back in bio class, my professor said that in lab tests, replacing the non-protein-coding dna with something man-made hasn't been shown to have any effect. (Removing it does have an effect).
