"I firmly believe this technology will create business value" is so obviously and categorically different from "Humanity has birthed a silicon god that I have also developed romantic feelings for" that I'm not sure if your comment is even trying to be in good faith
Not true. You can't really train your muscles to use less oxygen for the same energy output (what "oxygen-efficiency" would imply). You rather increase their capacity to take up oxygen from the blood and burn it. They will use more oxygen to output more energy.
That additional oxygen needs to come from somewhere. Endurance training at the same time trains the heart to deliver more oxygen to the periphery; the primary mechanism is increased cardiac stroke volume.

It's both. The idea that Ukrainian is an uneducated farmer's dialect of Russian is a common talking point in the "Greater Russia / Russkiy Mir" narrative. Conversely, asserting the status of the Ukrainian language is a big part of Ukrainian identity in the face of an imperial invasion.
