What They ought to incorporate into modern cameras

Whether it's a point and shoot camera, a smartphone, or an SLR, I think that there should be multiple lenses and sensors incorporated into a single camera; obviously (to some) some phones already have dual lenses (cameras), however, my idea is somewhat different: For example, have a high resolution 50 megapixel camera, alongside a 5 megapixel ultra high sensitivity camera, then maybe even have a third camera that is balanced between resolution and light sensitivity. Have one of the cameras be made to perform well under extremely bright light, while another performs well under, for example, moonlight alone. And maybe incorporate differing sensor sizes into the same system; for instance, you could build a compact camera with both a full frame sensor (for more narrow depth of field), as well as a 1/4" sensor in the same design, for having really deep depth of field for macro photography. And how about having a wheel that revolves to allow various filters to be installed on it, or have a rotating wheel to include different lenses or even sensors? Now let's get more onto the scientific side of things. Maybe someday we will reach that point, where we will be able to attain such a high degree of technological advancement, that modern technology might someday allow us to specify what wavelengths of light a camera can capture, by using a touch screen, joystick, or dial to enter in a specified wavelength of light that you might want the camera to capture; for example, I could one day have a camera wherein I could type in "250nm-350nm" and the optics might somehow change via quantum processes, or chemical reactions, to attain the resulting wavelength, or color, of light down to the nanometer, or even smaller increment. Of course, if, for example, you'd want to do something crazily specific such as 400nm-400.1nm only, then you'd sure need plenty of light to achieve the perfect photo. I mean, this idea of dialing in a specified range of wavelengths of the electromagnetic spectrum will probably not find itself useful to consumer photography, but I'm also thinking outside of the box, and "blending" into scientific approaches. Imagine if you could also see a live view, or at least preview, of the changing light as you dial in "green" or "red" and it applies the correct colored filter to the photo. In fact, we could also say that it might even be feasible to do so using voice commands! Imagine: "I want to capture the range of light 350 nanometers to 450 nanometers, and the camera captures that exact range of color (the light spectrum). That could really be worth the effort, just to see what the implications could be and what results could be achieved. I think that it's truly neat to see how thermal cameras, IR cameras, or UV cameras see things, although we could actually explore the deeper reaches of our own visible spectrum, by focusing in on a very narrow part of the spectrum...perhaps that is so. And to take it even a step further, what if we could then map photos that might have been taken using various ranges of light? For example, we could take a photo at 365nm-366nm, map it to the blue channel, then have a 367nm-368nm photo to map to the green channel, and finally, take a photo at 750nm-850nm and map that out to the red channel...I'm not exactly sure about what the implications of such an idea would be, although I can say for sure that it would be a really compelling experiment to achieve! One of the applications that I think it would be useful for would be black and white photography, and it would arguably be even better than Photoshop, and all of the "processing" would be done in-camera. The metalens idea seems really interesting because it seems like you could probably design a pretty poor lens and have it be outstandingly sharp, even on today's cameras, if it could focus all light wavelengths into a single place...
