I agree that the smartphone killed the point and shoot industry, but I think it's pretty far overboard to say that Apple is revolutionizing the camera industry with the iPhone 7. They added another lens, which is certainly nice but not revolutionary, and they added some depth of field effects, which are nice but look pretty bad compared to actual shallow depth of field.
Edit: Also, you definitely don't need to fire up Lightroom to share photos from your DSLR; I think practically any DSLR can shoot JPG. Many DSLRs can also share photos to phones via wifi or Bluetooth these days. Mine didn't come with such a feature, but Nikon sells a $20-30 adapter that adds that capability.
