That was just one example of what the mission could have been. What should the mission have been? My point is everyone can say they are betting on a non-changing thing and in retrospect it's easy to see what it could have been (in this case one of several, different ones). You've even expanded on "capturing memories" to make it "capturing images and memories" despite the fact they often have nothing to do with each other (medical imaging isn't related to memories, and diaries aren't related to images). So what do they do? Go for the most abstract (read: big) mission possible? Why not "we are focused on making people happy". It doesn't change. People want and pay money for it.
