A post sort of about digital cinematography

I know people have been talking about this a lot, especially in the last five years. I'm not going to say it's 'hotly debated' because it seems everyone has just lay down, and every now and again, a new camera or codec or system just comes along and rolls over everyone. I know it's probably all been said, but I feel as a cinematographer (instead of dressing for the job I want, I'm  just going to start describing myself with the job that I want) that will be entering into the industry just as film hits rock bottom, I'd like to just give my two cents, or maybe just sort of talk it out to the internet. Yeah, let's call this a 'talking at the internet to deal with my feels'.

I am quite aware that I have a lot to learn (and catch up on) regarding the advent and technology of digital cinematography, so I guess consider this a semi-ignorant, probably over-passionate rant.
