Adobe are developing on a feature that will automatically select the subject or subjects in a photo, so that you don't have to spend time using the magic stick, or carefully drawing around an object. The feature should be available in a future version of Adobe Photoshop CC, and uses "machine learning" to intelligently restricted the subject(s) in the photo. You can watch a video demonstration below.
From Adobe: "We’re excited to give you a sneak pare into one of the new functionalities coming to Photoshop CC. Select Subject, powered by Adobe Sensei, is a tool that enables users to make their picks in one click. With Select Subject, you’ll be able to get started with your selections faster than ever before."
