I'd be more optimistic. Tools are better today. Machines are faster. Re-inventing the wheel isn't nearly as costly or involved as it had been. Look at how much has already been re-done and re-tooled in JavaScript. The same process is being replayed in Rust, Go, and Clojure as we speak. As for the C machines, Moore's law already has a foot in the grave. Ten years ago, we would have just assembly-optimized any inner-loop bottlenecks and assumed that in a few more months Intel would get us the rest of the way there. Now I'm seeing more and more being pushed off into GPUs and custom ASICs. With clock speeds topped-out, the mainframe approach of pushing more into the hardware grows increasingly attractive. That, and so much is written in other garbage-collected languages today that LISP-friendly hardware could benefit Python/C#/Java/PHP programs as much as it would LISP ones.
