Retro lisp machines are cool. Kudos to the team. Love it.
That said… we need the “lisp machine” of the future more than we need a recreation.

What does a Lisp Machine of the future look like?
There is Mezzano [1] as well as the Interlisp project described in the linked paper and another project resurrecting the LMI software.

I love this quote (from Interlisp-D: Overview and Status):
"Interlisp is a very large software system and large software systems are not easy to construct. Interlisp-D has on the order of 17,000 lines of Lisp code, 6,000 lines of Bcpl, and 4,000 lines of microcode."
So large. :)
