I voted that there has been no impact. Yes, technology has made some aspects of photography easier and more accessible, but photographs that stand out for being aesthetically pleasing have always been the exception rather than the rule and have been a reflection of the photographer's vision rather than the technical abilities of the camera. If anything, I was tempted to vote that photography has had a negative impact in that there are now so many photographs floating around in cyberspace that it has made it more difficult to find the ones that really hit home.
On the other hand, digital technology has made it easier to instantly view the picture you've taken, enabling the photographer to see whether they have successfully caught "the decisive moment" but, by definition, decisive moments can't be repeated and you've either caught it or you haven't. So really nothing's changed.
