The learning of a musical instrument is a great metaphor to our shifting world. An instrument by its nature is difficult. You learn it through discipline, one small step after another, till one day, many years later, you feel comfortable holding it and skilled at playing; it but still, the nagging feeling that you know absolutely nothing about it persists. A guitar, piano, the trumpet, the tabla, they're infinite in regards to mastery.
Now, as we shift from an analog world to a digital one in all aspects of life, we also change the relationships of process with regards to analog tools. Our traditional instruments are analog. Our most recent instruments however are software (and in fact, they don't have to represent an analog doppelgänger), and as is the nature of digital tools, constantly changing and updating. Although the base of said software might remain the same through the course of its development, it is in continual iterations. Software instrumentation is also non-linear, automated, capable of interacting with many inputs and outputs and sometimes capable of creating its own musicality with just a set of parameters without even being "played" (a theremin on binary steroids). Our analog instruments do not work in this capacity, for the most part.
The other key difference is that often, the actual recording software (DAW) is the instrument. This mixes both the instrument(s), and the recording, in one space. This obvious insight might not seem important, but think it through. When I first picked up a guitar, I had no idea that one day I might learn how to record music. But, kids with an iphone or ipad start recording immediately. The instrument is just one piece of the recording puzzle. And we are now handed the recording capability first (without even asking for it in many cases), then the instrument. This is a complete flip of process. This gives precedent to the making of music, as opposed to the playing of music.
So, the process is different. Software is by it's nature, much easier to understand, and the brevity of it's learning curve makes proficiency come at a much swifter rate. People do not spend a decade learning a piece of software and then suddenly coming to an "aw haw", a moment of absolute clarity that happens periodically to players of analog instruments. Mostly because software gives a much swifter response to hardship. With software, you are ready to go after browsing a manual, checking some tutorials, and chugging a huge cup of coffee blended. Of course it helps to have a musical background, but its not a necessity to get started. Sure it gets more difficult when you expand your range and tools, but, it wants you to learn it fast. Your muscle memory is never tested.
This is a non-judgmental observation. This is the reality. If you are a teenager thinking about music, a small investment (or, ripping) will get you started, almost immediately. In fact, an intro software is probably included on your phone or computer already for free. In roughly two years, with some tenacity, talent and luck, you might have uploaded a song on Youtube or Soundcloud and have thousands of people hear it. In the old world, two years on a guitar might not even be enough time to get you in front of 10 people at your local open mic'd coffee shop. Just look at the ultra youngster electronic producers who are making hit songs, all by themselves and in record time.
Just like everything else in this new world; we are glued to our screens and creating everything inside a little box with a backlight.
