Digitial is the next big step across the whole planet from Amazon to self-driving cars (yuk). Inasmuch, Ray Kurzweil changed keyboards (as did Moog, but more so with digital sampling vs. analog wave transformations). Leo electrified a guitar and someone turned up an amp too loud.
I have to say digital guitar modelling appears right now as the next big step in our world (see FAS Modern 1 where no real life example sounds like it - yet it's a stellar sound.) and Cliff is certainly a leader in this community of real time digital guitar amp and cab modelling.
Yes, sharing digital (music) files easily and without compensation has changed our world; I'm pretty sure the toothpaste won't go back in the tube, but it's simply shifted focus to live shows and much more access to recording and distribution to the little guy ... no longer is recording and distribution of music the domain of large producers and labels. (I don't blame the changes we see in society on this however ... that's simply complacency and apathy towards a hard-won democracy and meritocracy which folks don't value as much anymore now they've figured out how to vote themselves OP$.)
I don't expect to see the guitar fundamentally change unless strings and fret boards go away. Pianos have been around for hundreds of years and don't require "improvement" or evolution (other than they now can sound like any other instrument with Ray's foundational work in digital sampling-based synthesis).
Therefore I too would suggest that Cliff is onto something remarkable, and may lead us into new frontiers beyond amps and cabs, effects ... or not; we will have to see.
It's the journey, not the end which is important; have fun playing your rig
