Stephen Wolfram continues to shy away from the understating, unexagerrating language that is the norm in the best technical, scientific literature.

His writing is dominated by the I pronoun, and he keeps creating these complex sentences just to make sure it is clear that it was him who thought about that, and he concluded it, and it is his contribution, only he saw the connection, etc.

IMO this is distracting from the ideas themselves, for what they're worth.
