I've stopped caring what the capacity is. Youtube doesn't require a fraction of what we have already in place.
However, they've put so many ads that an adblock is required.
But, if you have adblock you need to click the video you need to watch, let it not load, refresh the screen, wait way longer than should be needed, and then watch the video while getting a nagging popup that says "Experiencing interuptions?"
Followed by watching the video rendering NOT rendering at various points, and you need to pause and let it buffer.
All because google thinks they are entitled to push malicious ads onto my device, and punishing me for blocking them.
The speed we have is more than enough for the internet we have. The bottleneck is the companies enshittifying their own service.
Faster speeds mean nothing when you artificially throttle them.
