Why did the 4:3 aspect ratio die? Everyone says watching videos

You're almost demonstrating in that picture why it doesn't matter. 4:3 doesn't give you extra vertical pixels, it just makes your screen square, if you want more vertical pixels get a higher res screen.

on 16:9/21:9 you can run two windows side by side, i often have a video playing (maybe youtube) and surf on the other side.

4:3 is stupid.

That's because that 4:3 laptop is older than you.

For a more recent comparison - iPad Pro has a 12.9" 4:3 screen with a 2732-by-2048 resolution, and MBP has a 16:10 13.3" screen with 2560-by-1600 resolution. So you get an extra 448 vertical lines on a screen that's smaller.
On external monitors widescreen is okay, you're not gonna run out of vertical real estate on a 24" monitor for most tasks, but on small 13" notebooks 16:9/16:10 makes no sense.

humans see in 4:3

And the opinions of those people are as valuable as the economy of Yemen.
