Lisp lost in a much more profound way recently, and it's very rare to see anyone mention it, especially on the Lisp side of the conversation.
Over the last 10 years or so, we have come to the painful conclusion that mixing data and code is a very, very bad idea. It can't be done safely. We are putting functionality into processors and operating systems to expressly disallow this behavior.
If that conclusion is true, then Lisp is broken by design. There is no fixing it. It likes conflating the two, which means it can't be trusted.
