If you subscribe to the theory that all exposure (no pun intended) is good, then the new instant photos will bring more attention to photography and to yourself. It is not necessarily a bad thing, it is just the evolution of the form.
Ultimately the public will decide if your version of an image is better than another and if so, whether it is worth investing in. Art is so very subjective and always has/will be.
I wish you the very best.
