What a camera does is a translative operation of something already existing in front of the operator, it cannot conjure things on its own (whether original or derivative) nor scale due to the aforementioned limitation. It cannot understand instructions that are beyond the processing of whatever it is pointed at (leaving the rampant post-processing becoming the norm in handheld devices aside) and act upon them to significantly change the content of its output (whose object light last reflected from and how). Isn't this a very reductionist analogy? I genuinely do not understand its purpose.
