The answer to this key question is the improper use of technology. OCR i.e. Optical Character Recognition was one of the widely used features in the conversion of the handwritten script to an editable electronic format. While OCR techniques have developed drastically by 2020, when the movie was in the process of development before its release in 2006, Optical Character Recognition’s technology was not quite at par. If you recall, it was a time when the Apple iPhone 1 was not even launched so definitely that can give you an idea of the picture quality at that time. Since OCR majorly relies on using images of text to convert them, there were a lot of typos in the bee movie script.
