It won’t replace it, but it’s very likely to supplant it, just about destroying the segment by reducing demand by being good enough and so much cheaper, especially as people get more used to it.

Typesetting. Music engraving. Bookbinding. The quality of all these fields have been materially harmed by advancements.

Computer typesetting has, by and large, been a significant regression, though the gap has largely been made up now if you make the right choices.

Published music scores used to be set by experts. Now they’re set by novices using software that is mechanical in method and generally quite insipid. Most are atrocious compared to the old masters, and mediocre at best compared to the typical published scores from a hundred years ago; and very few popular scores are really good (… and if they are, there’s a reasonably high chance they’ve used GNU LilyPond, which has focused on this problem). But the barrier for entry is so much lower, and people have got used to the inferior results, so I don’t know if anyone engraves music the old way, and even people that know better largely just shrug and make do with the new. Like with computer typesetting, there is hope because things have slowly improved. But most will continue to be mediocre.

Books used to be bound with cold glue. It takes time to set, but the results are very good, supple and long-lasting. Then along came hot-melt glue, and it’s just so much friendlier for cheap manufacturing because books are finished within a few minutes instead of a day or two, that I don’t think anyone produces books the old way any more, even though the results are abysmal in comparison (compare the binding and reading experience of a paperback from the ’40s or ’50s with one from the turn of the century; no one after tasting the old will desire the new; for he says, the old is good). But they’re just (barely) good enough. Unlike the other two, I don’t think there’s any hope here—the regressive advancement crowded out the superior but dearer option so that no place was found for it.

You can still get relatively good published music scores from a few of the old German shops (Schirmer, Henle, etc.), but they are very expensive. They are a joy to use when playing, though, since the music is very clearly laid out and page turns are in the perfect place, etc. Finale and Sibelius are controllable enough that you can use them to do fantastic layout, but many people either do not understand how to make a score readable or don't care enough.

That, and what GP describes, is what I see as the overall trend of the market to hollow out the middle. It's not just about technology (though it plays a big role), as all optimization coming from competitive pressure - materials, processes, business models, marketing.

What seems to universally happen is, the market bifurcates - one part is in a race to the bottom, the other (much smaller) aims for super premium tier (overpriced quality), because only those two positions are sustainable, once the race-to-the-bottom side drags all the economies of scale with it. So as a consumer, you get to chose between cheap low-quality garbage that's barely fit for purpose, and rare, super-expensive, professional/elite high-end products. There is no option for "good value for reasonable price".

This has been happening to everything - software, furniture, construction, electronics, vehicles, food, you name it.
