A few weeks ago, I awoke one morning at 7 a.m. to a flood of messages in my email inbox. All 48 messages linked to a new video that had gone viral overnight. In the video, Robert Downey Jr., star of the Iron Man movie franchise, presented a customized 3-D printed bionic hand to a boy named Alex Pring, one year younger than my son.
Each email said the same thing: “This is amazing! Immediately thought of you.”
