yeah certainly the data has to be transferred somehow, the machine cannot read your mind, but I think being able to have a "conversation" effectively with the algorithm will go a long way. for example:

"portrait of woman, age 25, beautiful face"

"okay, face is good but make the photo more realistic and less artsy, and have her wearing a black turtle neck"

"okay, now let's work on the background, make it lighter and blurred slightly"

et cetera
