An interesting set of thoughts on 2001. Good art can make you think beyond the outright explicit meaning of the artist, which is the case here.
2001 is based on a collaberative story effort between Stanly Kubrick and Arthur C. Clarke. In fact, its genesis is in the Clarke short story, 'The Sential'. Though Clarke's novel and Kubrick's movie share some surface variances, they share the same basic story premise with each author telling the story in his own medium. Thus, the book can, and does, explain more because it is an explict narrative.
The suppositions of this flash presentation are not supported by the historical record recorded, by Clarke, of the development of 2001. However, again, they are interesting thoughts in their own right.
