It's hard to evaluate art without the context of its origins. Michelangelo's works were done in 15th and 16th century, so it's quite obvious that similar art, no matter how detailed or precise couldn't have been considered revolutionary at the beginning of 20th century, but it turned out that Picasso's "grade schooler's work" has been.

Another example of this is Andy Warhol's "Marilyn Monroe" that was just sold for $195M. Currently, you can write a neural network that will create better looking portraits, but it wouldn't convey any of the context in which Warhol first created his pop-art.
