In your opinion, has SLR photography been impacted by mobile phone photography?

The reason why SLR cameras have complex, comprehensive and difficult-to-use operations and functions, and are equipped with a large number of lens groups, is that SLR cameras have been designed and manufactured from the beginning as precision instruments for professional photographers to shoot high-quality picture content. Shooting things that people can easily see and shoot in their daily lives is only part of the camera's function. Its performance is mostly used in some professional fields, such as commercial photography, landscape photography (non-tourism photography), portrait photography, product photography, architectural photography, and some microscopic or experimental artistic creation. Simply put, this is because these users actually have no rigid requirements for the performance of SLR. Whether SLR is used or not has little effect on the content you want to shoot, such as the sister who bought a micro-single or SLR and wanted to take beautiful photos, and the elder who bought a super professional lens to travel, such as the freshman who heard that he bought a SLR to send his sister, may not be satisfied with what he shot with SLR. If you want to present a good result with a SLR, it is a combination of three steps: preliminary preparation, shooting skills and post-retouching. It does not mean that there will be a good result with a SLR. In many cases, the original picture taken by SLR is even more ugly than that on the mobile phone, because SLR tries to restore the unprocessed picture (the algorithm is different, so you can make post-production to meet your requirements for the picture).
