I think FT8 is just one aspect, I don't think you're going to see CW/SSB die off because of it. FT8 has some pretty strict timing requirements for instance that make it hard to use as a portable station.
I think ham radio is split between the people who like the social/contest aspect of it and those of us who like to tinker(and a subset that covers people who like both). 97.1b pretty clearly lays out a mandate to advance the state of the art and I think it's pretty incredible to pick out a message -20db below the noise floor.
