> With DSLRs my main complaint to this day is still the lack of a good modular lens system for phones (I understand some of the challenges and tradeoffs). For most people's camera habits (selfies, food shots, group pictures...) the lenses your modern flagship phone provides are mostly great.
Point-and-shoot cameras have been replaced by phones; DSLRs, on the other hand, are rapidly being replaced by mirrorless cameras. Mirrorless cameras, at least on the surface, seem to be an improvement on DSLRs -- they don't require a mirror, so they're both easier and cheaper to manufacture, they allow for modular lens systems, and even allow for more features (like shooting video as well as stills) than a traditional DSLR.
