First, let’s assume we’re all intelligent people here and not be condescending.

I am not saying it’s not possible to view high resolution content at 25 mbps. I am saying that certain content just can’t encode at full fidelity at 25 mbps. In my experience, high action scenes with tons of entropy to encode do not compress well. And those scenes degrade and become muddy or pixelated at lower bitrates. Do you need it for the entire stream? No. But sadly, to save on bandwidth many streaming services also severely limit how much buffering their clients will do.

Even all this said. We’re talking about 10’s of megabits of difference. Significant portions of the world have managed to offer gigabit internet to practically everyone in their jurisdiction. And yet, we’re here in the dark ages with 25/3. And sure, you could say “American has significantly more rural areas, those customers are hard to serve.” But, I’ve got family in coal-country West Virginia that have gigabit fiber. There are no technical hurdles. These companies just don’t want to upgrade their infrastructure.
