It's pretty different. If nothing else, it's playful with Feynman—almost done in jest as an aspect of the rogue part he often played, and largely innocuous. Others have already written about the issues with e.g. New Kind of Science at length so I won't go into it, but if you look at the specifics there and ask whether they're things Feynman might also have done, it's easy to see the resemblance is pretty superficial. Feynman's non-autobiographical writing was pretty down to earth imo.
