You can learn to play the guitar, and buy a guitar, but it's very hard and expensive to also learn the 3-4 other instruments you need to make a full song. (my brother learned both the guitar and percussions; this took a lot of time and was quite expensive, if he had a tool like this he would probably focus on the guitar and just rely on this to generate a background track)
Learning something difficult is rewarding on several levels. To boil it down to just the intended outcome is a rather narrow view of the matter.
let us side step the binary "privileged" argument which is disruptive here.
The issue for us now is given that level of talent, would Hendrix, Johnson or anyone else be able to make a career in 2028? Or will it be the preserve of people with free time and money?
There are a million things you _wanted_ to do that you'll never get to do. And that's unfair.
Shouldn't we aim for a future that is the exact opposite of this?
What work?
If we assume the above to be correct then the "cheap" guitar is an additional cost whereas the AI music model isn't. In addition, guitar lessons cost money and spending time practicing is harder for some people than others due to their circumstances.
