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.

There is Mezzano [1] as well as the Interlisp project described in the linked paper and another project resurrecting the LMI software.
Depends on what one means by that.
Dedicated hardware? I doubt that we’ll ever see that again, although of course I could be wrong.
A full OS? That’s more likely, but only just. If it had some way to run Windows, macOS or Linux programs (maybe just emulation?) then it might have a chance.
As a program? Arguably Emacs is a Lisp Machine for 2025.
Provocative question: would a modern Lisp Machine necessarily use Lisp? I think that it probably has to be a language like Lisp, Smalltalk, Forth or Tcl. It’s hard to put into words what these very different languages share that languages such as C, Java and Python lack, but I think that maybe it reduces down to elegant dynamism?
Since we're now building specialized hardware for AI, emergence of languages like Mojo that take advantage of hardware architecture and what I interpret as a renewed interest in FPGAs perhaps specialized hardware is making a comeback.
If I understand computing history correctly, chip manufacturers like Intel optimized their chips for C language compilers to take advantage of economies of scale created by C/Unix popularity. This came with the cost of killing off lisp/smalltalk specialized hardware that gave these high level languages decent performance.
Alan Kay famously said that people who are serious about their software should make their own hardware.
