I have had the same thoughts before and come to a similar conclusion. I believe it's not about the language. It's about the features: runtime code editing, single address space, program interoperability. Lisp could be replaced with C or anything else. Unfortunately this is the hard part. No one is about to design completely new hardware or architecture for this, as it makes no economic sense. So we just get a shiny new language every few years, and nothing really changes.
