I agree. The tool itself can't kill creativity that wasn't there to begin with. Most people, let's face it, are not particularly creative and are going to go for the easiest option to obtain their purpose. In this case, it's a snapshot using a cell phone instead of using a point and shoot. The difference is that we all now *constantly* have our cell phones with us, and taking a thousand pictures doesn't cost a thing, so people simply take more photos now and have more ways of sharing. So it's not that suddenly everyone is lacking creativity because of Instagram photos. It's just that now, we can very easily see all the crappy pictures people share. We don't have to sit through boring vacation slideshows anymore.
I'm reminded of what a friend of mine in Turkey said once: "We don't have a lot of handicapped people in Istanbul." I said, "My bet is that you have a LOT more than you think. You just can't *see* them because the sidewalks are narrow and uneven, curbs are about 2 feet tall, there are stairs instead of ramps, and no handicapped access to buildings."
There have always been PLENTY of crappy, unimaginative pictures. We just couldn't see them all like we can now.
The AI tool, I'm sure, can be used by creative people to create a new art form. It can also be used by creative but unethical people for very nefarious purposes, which is honestly my only real concern. The same tool is also probably going to be used in very banal ways for very banal results by the same people who have produced banal, filtered cell phone shots. For them, it's a shiny new tool, and as soon as they are distracted by the next shiny new tool, they'll move on. The creativity is in the person, not the tool.
