Shouldn't phones kill cameras wholly? Mirrorless have some technical hurdles to overcome still. But I'm sure in twenty years they will be replaced by AR glasses controlling drone-mounted cameras.
Honestly, everyone is worked up about mirrorless ILCs, but I think the really interesting photographic advancement is happening in phones. I don't think phones will completely replace dedicated cameras, but they do seem (to me) to be a tool which will incentivize innovation and software advancement.
Think of it this way - most people have a phone with a camera on them at all times, and the camera has become one of the key features which drive people to upgrade their phones - people pay more to get a better camera on their phone. Phone cameras are inherently limited by their size, so manufacturers have to look for creative ways to advance performance. That incentivizes manufactures to invest in new systems and now many phones can use creative software to replicate (to some extent) the features which were previously limited to expensive and bulky equipment. Further, the open app development market means that the way people take or consume photos changes rapidly as well. Being able to take a photo and share/send it immediately was in my mind truly revolutionary.
While it's really interesting to see these developments, I'm more curious about how the ILC manufacturers will look to maintain a distinct identity and niche for their products. They have already tried to bridge some of these gaps by giving ILCs wifi which let you get photos from the camera to your phone so you can share immediately (like a phone), and they continue to stand apart by unparalleled capability and flexibility compared to a phone. But what happens which camera manufactures start looking at the automated features being found on some phones? For instance, I think I remember seeing an article which indicated a new phone came with a camera AI which actually reviewed a photo as you take it and gave you suggestions on improving your composition. Personally, I'd hate that but I would bet that some new photographers may like an assistant like that. I'm really curious to see where camera phones push the ILC market (if you can't tell).
