Title is inaccurate; the article doesn't say anything about why, which is what I was interested in. And it's exaggerated anyway. The title should be more like, "Musicians Make Us Weep More Than Computers". The article didn't really say anything that isn't already known.

The accuracy of the conclusion depends on how the computers played the sonatas. I would hope they were programmed to play with variance and imperfections, otherwise it’s more like comparing beginning musicians’ rote performances to professionals’ emotive ones.

Computers make me tear my hair out.
