Yeah. They are quite literal. You have to type in F One Eleven for it to say things right, which happens a few times in that video.
Technology often tricks us into a false sense of security. That guy was probably thinking it would be easier to just type it all out, proof read it and then let the confuser narrate it in one take. But the author was ignorant of the fact that you can only truly trust a computer after it's been thrown through a window.
I assume he did watch it and would have proof listened it after it was published for the whole world to see but by then it was too late and the old warbird just wasn't worth going through all that work again just to fix minor details like the plane's name designation.
I have a feeling that even though I liked the video, I think that there's a good chance it was put together by one of those instant gratification millennial types who wouldn't know what a good work ethnic is if one showed up in person and took his job.
