Why are automated digital voices used here? MAKES NO SENSE and difficult to understand. Would appreciate the same presentation with a human voice thank you.

I would love to watch this video all the way to the end but I just can't stand the voicing. Its so annoying to me that it is hard to concentrate on the actual topic.
