You could've also asked if people still wrote assembly in the age of compilers, and the answer would be the same. Sometimes we want/need to control or understand what is emitted by the tool.

However, I want to point out the obvious fact that people are still playing the piano in the age of the self-playing piano. Humans are experiential creatures, and we enjoy a wide range of activities for their own sake that may have nothing to do with efficiency of output.
