Since the 1980s, popular music has been dominated mostly by synthesizers and other synthetic devices such as computers and drum machines. Once in a while, acoustic instruments like guitars or pianos used in popular music but their role in the songs are limited. Even the more "organic" and "earthier" styles of music such as country music have some electronics and computers added to their sound.
During the early-mid 21st century younger people are starting to take interest in acoustic or "real instruments" that require talent and skill to play instead of having some computer program be the "musical instrument." The could be a result of the Digital Rebellion generation that come of age during the 2030s and 2040s. As Artificial Intelligence becomes more advanced, computers and other machines can write their own original music. But more and more people are starting to believe that human-made music with real instruments has emotion and soul to it, along with skill instead of pushing a button to make music.
Electronic and synthetic elements in music will still be around, but eventually "real instruments" are added to the electronic sound. Instruments that were not popular in mainstream music such as oboes, clarinets, and bassoons will be included with the music. Fuller orchestras and bands will make a comeback in pop music instead of having the synthesizer replace the instrumental tones.
