Technology changes all the time, and those changes are driven by us. However, it's interesting to consider how technology changes us, how technology changes our perceptions of culture, of art, and of entertainment. It's not just about technology will change the platforms artists (of all types) use to create, produce, publish and distribute their work—but how technology might even replace the artist him/herself.
Consider entertainment. I see this as the area in which we'll see technology changing us. For millenia, we have watched or listened to entertainers perform, either live or recorded. But enter the vocaloid: a computerized voice that uses samples from dozens of performers to create a voice of its own. In Japan, Hatsune Miku is a popular vocaloid. And the entertainment industry has even advanced the vocaloid to more than just a voice. Hatsune Miku also has a CGI avatar "body", and via "virtual presence" performs "live" with her own band in concerts.
Arguably, vocaloids are beginning to rival humans in popular entertainment, at least in Japan. But Hatsune Miku and other vocaloids weren't even the start of virtual entertainers. During the height of her popularity, video game character Lara Croft (of the Tomb Raider game series) was "hired" to pitch Lucozade energy drinks and SEAT cars in 1999.
You may also remember the (short-lived) Ananova who was the first computer-generated virtual newsreader; visitors to ananova.com (website no longer active) could watch and listen as the virtual Ananova announced the latest news, just like tuning into CNN. And sometimes I think I'd rather listen to a computerized news anchor rather than some of what we see on Fox News and other news channels.
In 2001, the computer-animated movie Final Fantasy: The Spirits Within took things up a notch with the first "syn-thespians." Here, protagonist Dr Aki Ross and the entire cast were actually realistic virtual actors, generated by a computer. Ross took most of the attention from the movie, presenting a very realistic virtual avatar that captured public interest for a time. Named #87 of Maxim magazine's Top 100 Hottest Women of 2001, Dr Ross "posed" for the 2001 "Hot 100" issue, and even appeared on the cover in a purple bikini. (Along the same lines, Lara Croft had previously been a virtual model for real swimsuit designers in real print ads, but I'm having trouble finding a link. There's the expected flood of Google results if you search for "Lara Croft swimsuit".)
The DVD release of Spirits Within experimented a bit with the limits of virtual entertainers. In a DVD extra, the virtual cast (led by Dr Ross) performed a dance cover of Michael Jackson's Thriller.
Similarly, see the (intentionally humorous) Courtney Gears from the 2004 video game Ratchet & Clank: Up Your Arsenal where she sings about the impending robot uprising. Compare that to any music video from Britney Spears at the time, or most pop stars today, and you'll see little difference. I even had the Courtney Gears song as a ringtone on my phone, once upon a time.
I suppose it's only a matter of time before someone at a music label gets the bright idea to combine data analytics of what people are buying, CGI avatars, and vocaloids to create a completely synthetic pop star, sometimes called an idoru. The first stage might involve having a computer analyze the traits that people focus on with pop stars—gender, face and body type, hair, voice, etc—and then feeding that into a computer system a la IBM's Watson to create a virtual pop star that is geared to be popular. Do a few pop rock covers of popular 80s and 90s songs, maybe have a really popular songwriter compose a few original hits, just to try it out. Music videos could be awesome—imagine a singer who's in perfect sync with the backup dancers! If "she" becomes a hit, the studio can crank out song after song after song. And if "she" is like other pop stars and "her" popularity wanes after a few months, the studio can just rotate to the next virtual pop star.
