The hope was that PSK63 could replace RTTY, being both spectrally more
efficient, and more usable for a panoramic presentation for contesters
to see who is on the band, but it never came about. Too bad, I think,
because it would help reduce congestion during contests. PSK63's overall
time to complete an exchange is roughly equal to RTTY (twice as fast as
PSK31), which is considered too slow for "RTTY" contesting, but I don't
understand why it has not been adopted. I even wrote an article on PSK63
for the National Contest Journal, but there appeared to be little
interest and few comments.

I don't think digital voice will ever replace SSB, any more than PSK31
and other spectrally more efficient modes will replace RTTY. Radios
have a long lifetime. But unlike digital modes whose bandwidth is
fixed, phone can communicate using reduced bandwidth. Look what
happens in a contest.
