This is how I see it as well, and this is everything I dislike about said shift.
My personal view is that all tech should be readily accessible to the masses, but the masses should become more literate with the media they use, not have the mode of content delivery become dumbed down to accommodate a hypothetical lowest common denominator to the point where an advanced user no longer has any control of their media. Familiarity with the content is going to naturally lead some people to wanting to learn to control it better, and I don't think that option should go away entirely. Maybe I'm oversimplifying the issue, and it's simply not possible to offer advanced control in an accessible manner.
It's just got me imagining this campy future with banners reading, "when there are no more advanced users of computers, only computers will be advanced users."
