Writes the book as if humans are morons that should have been able to achieve every thing they have in history in like 20 years instead of the thousands of years it took. the only saving grace is the knowledge givin in the book once you get past the high horse writing style. Just read the knowledge it's even credited in this book.there are only a few things book has that the knowledge doesn't and most of them are part of the physical copy as they are measurement on the book cover that are size acuret.
If your looking for a historic comedy filled book you could also read A Connecticut Yankee in king aurthers court
