To be fair, game developers have been rendering text on the GPU for over two decades. I've done it in college a decade ago with bmfont [1] (nowadays the engine does rasterization during import). Whoever thought was making a case with "outputting text to a terminal emulator is a PhD level problem" was really out of their depth and was making a case for unnecessary inefficiencies. Kudos to Casey for proving a point.

I remember when that terminal situation first happened, and my main takeaway wasn't "wow, this Casey guy is a genius" but rather reinforcement of my pre-existing belief that Microsoft is full of incompetent and lazy people. Anyone who has ever dabbled in engine or low-level game dev has implemented basic GPU text rendering at some point.
