Will SLR cameras be eliminated in the future?

It will not be eliminated in the short term, and the medium term is in jeopardy. The existence of SLR cameras only relies on traditional optical technology in framing. At present, electronic framing technology is developing rapidly, and it is entirely possible to surpass optical framing in the medium term (five to ten years). The reason why SLR exists is that users have accumulated a large number of lenses, but that means it will be used for 20 years, and then it can't be said that it is not. It is a collection of a few nostalgic people.
