Well... I hafta put my two cents into this one...
Digital modes CAN be very efficient and very effective in their
use of spectrum. Consider PSK31 for instance, where you can have
several "conversations" within the "normal" passband of one SSB signal.
On the other end of the spectrum could be digital voice... Anyway...higher
symbol rates make for wider bandwidth signals, all else being equal.
On the other hand... all else Doesn't have to be equal. What I would be
interested in would be narrow digital voice. Hope we can get there.

With a sentiment like what I think that comment
represents, it is amazing that we still have any bands
at all to operate anymore!!!
Ponder:
Circa 1955 - "Great! More Donald Duck noise in the
bands. Just what we need!"
Circa 1930 - "Great! More voice signals in the bands.
Just what we need!"
Circa 1920 - "Great! More single tone pure CW signals
in the bands. Just what we need!"
Whether this particular mode is truly effective or not
for communications in the way that hams typically do
will need to proven over time. But to unequivocally
and offhandedly disparage it is counter to one of the
main "basis and purpose" definitions of ham radio -
see part 97.1(b).
