These lables are useful when you're seeking an audience for your movie. Did you shoot in black and white? You're wasting your money advertising to Millennials; they won't watch it. Handy to know!
I don't share the worry of your second paragraph. I'm "Generation X". And I'm sure we'll come up with equally lame lables for newer generations.
People always start off with a camera. I think this is a mistake. A camera is the easiest thing to borrow or rent, and it will be obsolete in about 20 minutes. A good shotgun microphone can last you a career, as can a trio of fresnels; if you have those, the movie you shoot on your iPhone will be more watchable than the one by the individual who owns an Arri Alexa and nothing else.
I've used jibs indoors, and they are (as Stephen says) a bit of a pain. If you want to follow actors indoors, I suggest a dolly, Steadicam-style stabilizer, or motorized-gimbal stablizer (depending on the effect you want and the location itself). All those take up less space in use, and are more easily reset for different shots.
I think the angles of super- and hyper-cardioid are reversed in the summary text. A hyper-cardioid is narrower.
Gah! Does Adobe even run their applications *one time* before they push them out to their unsuspecting suckers? I've tweaked Dreamweaver 2017 so now it crashes only two out of three times when opened. Photoshop 2017 can open *almost* all the files that I created with 2015, and Acrobat can open *most* PDF files. And sure, Premiere Pro 2017 will just *lose* an asset or six from time to time, but it is an improvement over 2015 in that *when* it crashes and corrupts your project file, you can *usually* recover your work.
Huh! Different strokes. Every set I've ever been on, not taping down your cables is a quick way to get yelled at.
