Why was this downvoted?
This isn't very clear in the video, because the editing process in modern software is very non destructive, so you never actually "make" a new sample. In the more primitive hardware of the past, the process is much more explicit.
If you have some other point to make about creative/artistic legitimacy, you should just make it.
Which it clearly isn't.
Hence my first comment.
Sorry if this sounds mean, but you did ask.
So most people interpret would instead interpret it as snide commentary on the illegitimacy of sampling as an art.
Which most people also don't like.
Hence the downvoting.
