Google's own mistake? Look at the Google icon: Rene Magritte

At more than 10 o 'clock this morning, I opened the familiar Google and found that the icon was changed to a surrealist painting, ALT tag, indicating "Rene Magritte" (after 13 o 'clock in the afternoon, it was modified twice, respectively, "Rene Magritte", "Rene · Magritte ").
