My first reaction was...oh no, not another one. You don't even need to mail your cards anymore, they conveniently store them for you (vault concept).
There was an interesting comment about grading though...
" Lee said the company wants to add speed and transparency to the system with a new process that uses computer vision and machine learning."
Introducing objectivity and reproducibility into grading...now that would be impressive and valuable I think.
