This video doesn't explain what the project does and how it does it. Also it's deliberately misleading the viewer, for example it purposefully incorrectly states that C++ is an interpreted language.

Also the music is way is too loud and sudden.

The video is a compliment to the Github repository, the presenter even shows code and brings up the repo in the video. I guess you didn't watch that part and unfortunately you didn't get the joke either.

Well the video is almost entirely a joke and almost every sentence in it is ironically false; that's the point.
