That's what painters said when the camera was invented. The professionals adapted.
That's what they said when Kodak put an affordable camera and celluloid film in the hands of every Tom, Dick and Jane, practically wiping out the glass negatives industry overnight. The professionals adapted.
That's what they said when color film came out. The professionals adapted.
That's what they said when "common man" 35mm caught up with MF and LF as acceptable for weddings and other pro uses. The professionals adapted.
That's what they said when Edwin Land announced that you didn't have to send your film in to get it developed anymore, if you didn't want to. The professionals adapted.
That's what they said when Photoshop and other digital editing software came out. The professionals adapted.
Now, that's what you and a few others are saying because digital cameras have come out and gotten to the point where they can produce results that rival film. Instead of curling up in a ball in the corner of the darkroom though, the professionals have adapted again.
None of those things ruined photography. It's just a perception by people who can't seem to adapt to the inevitable technological changes that are taking place all around us all the time.
Technology in EVERY field and occupation keeps moving forward. Professionals adapt to those changes. They learn to master the tools, old and new, and use them appropriately for the given situation. They don't whine about it. They grab ALL the tools available by the hoo-ha's, master them, and make their mark on the world around them, and make a living at it.
If they can't compete against Facebook fauxtographers and noobs who just walked out of Wally-world with a $500 camera and nary a clue, especially nary a clue in the BUSINESS of photography, they should be looking for a new profession anyway.
By the way, how many centuries did you think celluloid film in a light-tight box with a lens screwed onto it would remain the "cutting edge"? It was inevitable from the day film came out that it would someday be replaced.
Like Andy said in The Shawshank Redemption, "Get busy living, or get busy dying".
That's just my opinion, of course.
