I'd say it depends. For me art is as much about the artist behind a specific piece as it is about the actual piece. I agree with the person you responded to. I want human feelings in my art, no matter how abstract, for it to truly speak to me!
Perhaps the Vogels https://en.wikipedia.org/wiki/Herbert_and_Dorothy_Vogel knew the artist? The way they amassed their collection is truly inspiring.
Picaso's wife infamously knew he was having an affair with his muse from glancing at a painting. But did every other Picaso fan who saw that same painting? Did truly know anything about the artist behind the picture?
So the chances of everyone else who appreciates an artist actually truly knowing anything about the actual artist? Complete rubbish, say I!
Take Turner, for example: turns out, the location of a lot of his pictures have been wrongly attributed! How everyone can claim to 'know' the artist and yet not realise that the picture is of Portsmouth or a lake in Scotland instead of Venice or somewhere else seems like they didn't really know the artist after all?
So there's a picture on the wall by Satoshi Nakamoto. You feel that genuine, because it's signed? Then when you get told that its painted by a bot, you feel cheated? Because you felt you knew something about the artist by looking at the art?
