Traditional cameras--and the more traditional you get the truer this probably gets--have been fairly, well, terrible is probably not too overstated in software. One could probably make nationalistic--or at least industry related--comments related to that but I won't. (BTW I have significant Canon and Fuji systems.) It's also probably the case that the buyers of those cameras were traditionally fine with software that was pretty hands-off.
But, yes, if you combined APS-C Fuji, say, with the software available in an iPhone you'd have a really impressive instrument and presumably we'll get there some day.
