If hypothetically targeted ads would be banned, there would be the same advertising budget as before
Not really. The 2x $1000 or so I spent on targeted ad campaigns have been worth it. If they weren't targeted, it would be far less effective; there's quite a few articles pointing out that targeted ads have a far higher click-through rate, and a higher conversion rate as well. Without targeting, my ad budget might still be $2000 but I wouldn't be spending it.
Acting - as part of "the arts" - is more play than work for the people who do it. That merits not automating it because without enjoyable things to do, we become nothing but consumption machines.
Why should the movie studio executives, board of directors, or shareholders care? To them, it's a business to maximize profit. You can do that if using AI costs less than paying actors.
during the filming, Alec Baldwin fired a live round from a prop gun that killed the movie's cinematographer.
Why didn't they make a movie about that?
Maybe they can put an OLED display behind an LCD panel to get double the colors.
IIRC Sony did something like that: they used an LCD panel to produce colors in front of a black&white CRT to provide the backlight. The result was a screen with a very high contrast ratio.
