As a dedicated snapper since 1971 it has indeed changed a lot. The main complaint I've heard isn't so much the death of anything but, rather the impact of the changes. Truly, the most innovative DSLR was the NX by Samsung which brought the smartphone interface to the DSL. It meant that ease of use from the snap to editing to posting was as similar as it could get to the convenience of a smartphone.
But, by that time even Samsung had realized that the DSLR was dead as a consumer tool and dump the camera; switching instead to improving photography with a smartphone. The smartphone did not kill the photo industry. But, rather it changed the camera industry so radically that no consumer camera company could survive.
Today, the DSLR is still around and still in production but is now primarily aimed at professional users, alone. (Remember, I said 'primarily'.) So innovation does not really kill anything, but it does have a real impact. The consumer camera industry of today is completely unrecognizable compared to what it was in 1971.
