I’ve read the book, although I think to be fair I gave up in the final monologue- which is just pages of excruciating exposition. The book just has one small flaw, Rand builds a world where her philosophy is true, and that world looks nothing like ours. It’s just absurd phantasy.
The beautiful thing is a funny jibe because it’s just so lazy to make your philosophically good characters physically superior too. It’s like if you put the slightest critical eye to the work it immediately creaks.
