You're exactly right. Let me support you by adding some examples:
- Look Mum No Computer: https://www.youtube.com/playlist?list=PLluPQLh1xzlLcJd9CbAxE...
- Caught in Joy: https://www.youtube.com/@CaughtInJoy
They just show their stuff, and what they can do with these. No talent, just show. /s
Look Mum No Computer is interesting.
On one hand, he's a bad example, because - at least as far as I know - he builds most of the stuff himself. So he's not showing off expensive synths he bought, which makes this kind of a category error.
On the other hand, he's a great example, because in terms of his musical output, he's a quite bland epigone of artists like Howard Jones or Thomas Dolby of the 80s. And in the playlist you linked of Wendy Carlos.
Now the thing is, I love Howard Jones, Thomas Dolby and Wendy Carlos. But they exist already. I don't need a copy. That's exactly the point I was trying to make.
I don't need yet another YouTuber recreating Axel F. on his freshly bought Jupiter-8. I want new Axel Fs!
