It's sound.
Long before GPT, image synthesis, video deep-fakes and these imagined "Photoshop for words", we had sound synthesis.
That's a very useful marker. Because we can read the things people were saying about the future of sound, their hopes, fears and predictions as far back as the 1960s when Robert Moog and Wendy Carlos were patching modular synths.
Most of the fears and predictions turned out to be rubbish. Musicians, orchestras and live events didn't get replaced. Instead we invented synth-pop bands.
And many of the things technologists imagined people would want to do, turned out to be way off the mark. To my knowledge Isao Tomita was the only talented artist to "replace an orchestra" with synthesisers. Most people who used the tools "as intended" were artless, and forgettable. Everyone else ran riot in the parameter space - messing and subverting the technology to get the weirdest punk-ass squelches and wobbles possible.
So I always have to look on these "How synthetic X is going to make the real X obsolete" with a pinch of salt.
