Because change is expensive, it takes away our fun and worst of all devalues skills some people have taken years to develop (pun not intended). It also runs the risk of reducing people's overall visual perception as they get used to a more general standard of image making, like MP3s have done to audio.
What skills exactly do you feel this phone will replace? Exposure? Sorry, but auto exposure had been around for decades now. Because it has a manual mode? Surely that REQUIRES skill to use. Light trail effect? You mean it has long shutter speeds? If you think using a long shutter speed takes years to perfect perhaps photography is not for you.
I'm not getting this thread really. It's a camera phone. How is it taking away your fun or devaluing your skills?
What it will NOT give you: Creativity, an understanding of light, the ability to recognise when you're pointing it at something worth photographing.
Photography isn't about technical skill really. Technical skills can be taught very quickly to most people... unless they're a bit thick. It certainly doesn't take years to be a good photographer... not technically anyhow. It takes years to be able to create great images though, but that's got nothing to do with technical stuff. How many threads where good photographers have used crap gear to create interesting work does it take to convince people like you this is so.
If you think your camera is responsible for your great photography, then you may as well give up and go do something else.
Also... this phone existing will in no way replace decent cameras aimed at those able to exploit them. This is aimed at those with no technical skills, but people with no technical skills can create fantastic images if they are creative. What's wrong with cameras that allow creative people to create interesting things that they may not have otherwise created? Why does that threaten you? You not creative or something?
The sooner the technical bullcrap is removed from photography, the better if you ask me. All that will then separate the good from the bad is the creativity and originality of the person using the camera, and maybe then people will stop being impressed by technical "skills" and start paying attention to what the imagery actually has to say.
