So far they all suck at low-light photography or moving subjects (or both at the same time like taking pictures of kids indoors at a birthday party). That would be a real breakthrough.

The optical image stabilisation & object tracking of our eyes is mind blowing. Optical illusions demonstrate the amount of interpolation that our brains to do aid vision / fill in the gaps of image detail coming from the eyes.
Not really intending to be an apologist for digital cameras nor disagree that they have a lot of room for improvement, but moreso just put it all in a different light.
Most people who only photograph with phones, even high end ones, don't seem to realize that similar gains happen in the camera sensors as well. And them being always much larger, they will always be ahead in low light and in signal/noise ratio.
