Except conventional CPUs aren't really glorified PDP-11s, except in the sense that they're Von Neumann machines with untagged memory; and the conventional CPUs started lapping the Lisp machines around the mid-80s, when 32-bit microprocessors started becoming common and Lisp compiler technology evolved to better support them.

And even the "untagged memory" bit might not hold; with things like CHERI, a LispM style architecture is due for a major comeback.
