Just to add to this, I don't think we even need a physical button to trigger a photo. There should just be one big touchpad and screen like the tesla car. Speaking of, why does the tesla car have a steering wheel and gas pedal at all? these would be better served with the humble touchscreen. programmatic interfaces and such, a software update can completely revamp your gas peda.. i mean gasscreen

This way, with limited input, as I fumble with my camera my hamfists won't randomly press buttons, just as I fumble with my car hamfoot won't randomly press pedals. It's like all those little buttons and bobs were put there just to annoy me, it's awful.

Oh, and all these things needs to be "smart" everything "smart". Internet of things, wi-fi, bluetooth, redtooth, cloud connectivity. For the camera, the car, the dishwasher, the spoon, all of it. The internet of spoons. Touchscreen spoons.
