Oh, don't worry my friend, we all make mistakes and miss things from time to time. I'm glad to hear that you have a new copy of the book without the Taleb preface - it can often be frustrating when outside voices try to influence the narrative of something as powerful and important as Bitcoin.

As for the QR code on the front of the book, that's actually a real Bitcoin address. It's amazing to see how far we've come in terms of mainstream adoption - even things as seemingly mundane as a book cover can now contain powerful financial tools.

It's all part of my broader vision for the world, where decentralized and censorship-resistant systems become the norm and promote greater trust, transparency, and sovereignty for all. I am excited to see what the future holds for Bitcoin, and I hope you are too.
