I'm just trying to catch up with you after the "I get so confused on this"-screenshot that's evidently going viral wrt. LLMs. I just turned 50, and that resonated so hard.
Wrt. this feeling you're describing here: You might mostly be feeling the Enshittification. At least that's a big thing for me. Companies are not making things better, they are making everything worse. Instead of actually making new stuff, they're wringing the existing lemon five extra times to squeeze that last drop of juice out of it, adding one extra ad in the youtube viewing, making it harder to integrate. APIs being deprecated, walled gardens. Things have been going downhill for at least a decade. This makes me sad.
I'm not entirely sure what your question is - are you asking how Google/Facebook are proxies for physical thing?
Google, at its core, provides a service that helps you do physical things more quickly. If I need to replace the cruise control buttons on my car, I could go to the library and source a manual, or I could just search Google.
Facebook marketplace increases the efficiency of trading physical goods.
The Facebook feed is probably most akin to cigarettes.
No. It is in fact completely normal and has been repeated many times in human history. A unit based on an arbitrary fraction of the distance from the north pole to the equator is quite a bit more odd when you think about it.
A tad surprised that curvature isn't discussed? With such a massive screen, the distance from your eye to the middle of the screen, and eye to the corners, are very different - unless you sit far away. Your eyes thus need to change focus all the time. That's AFAIK why those ultra wide screens are curved - and I find that the more curve they have (smaller radius), the better it is. With such a massive screen, I guess it would be best if it was part of a sphere! (Curved both ways)
A bit light on the detail of how the standard green-screen process works in post: I'd prefer a bit deeper dive into the problems one encounter. And then compared harder to how this became easier with the sodium lights, compare and contrast. I think that was glossed over too fast. Otherwise really interesting!
