The biggest threat I see is the inability for people to parse mass media of info. Stats says violence is down but we feel like it is worse. Because we see all the worlds problems in a one hour segment every day.
I've said flavors of this many times, and I really do believe this is one of the greatest challenges we face, today. Most people just aren't naturally equipped with the meta-sense to parse this stuff and come out the other side. I have no idea what the solution is.
Great, watching a movie to the sound of people munching.
I've watched movies at Alamo Drafthouse with people eating around me multiple times and have never noticed anyone chewing.
I'm pretty sure YouTube doesn't send you an unencrypted stream (anyone know for sure?). I've always assumed you run their EULA-bound, DMCA-protected software in order to decrypt that stream and watch it. Easy enough to save that, of course, but you have to bypass the DRM.
Depending on the quality, but at HD+ for sure, the videos are downloaded as video and audio streams separately from public sources, without any kind of DRM. It's possible to manually grab those files and mux them locally (that's what the player is doing in real time). I used to do that before I found an acceptable local downloader program that handles that for me.
Real Programmers don't write in FORTRAN. FORTRAN is for pipe stress freaks and crystallography weenies. FORTRAN is for wimp engineers who wear white socks.
