The GPU renders the map no matter if there is lighting baked in our not. It's exactly the same operation. And depending on your display tech, brighter pixels might actually use slightly less energy.
The brightness is too bright, not the color. The brightness is always a choice by the manufacturer they could easily make it dimmer using the exact same components.
Knowledge has benefits, that's pretty much always true. But it's not good to require everybody else learn a different system just because one single country feels too important to switch from their homebrew system like everybody did. It reeks of arrogance instead.
Woodworkers don't traditionally cut boards to 1 inch or 2 inches thick; they're rough sawn to that thickness and then dried and milled to 3/4" or 1 1/2". Which are 1/16th or 1/8th of a foot, and both are divisible by 2 and 3 and expressed in a power-of-two fraction. a third of 3/4" is 1/4".
Okay but then that third is more of a lucky coincidence than a function of the measurement system. That's like saying millimeters are good for woodworking because boards are traditionally milled to, say 18mm (incidentally almost equal to ¾") and you can divide that by 2, 3, 4, 6 and 9.
And I'd argue, dealing with fractions is still fundamentally harder. They number sometimes are or aren't convenient independent of the system used.
Nein, unsere "Christdemokraten" haben einfach angefangen das Wahlprogramm 1:1 von den Rechten abzuschreiben.
