ah your siding on the lisp machine vs todays hardware arch. I think if the lisp hardware architecture has significant advantages we`ll see that emerging in "soft cpu`s" on fpga`s. Particularly as the Xeon/FPGA gear gathers steam.

We've already seen the advantages although the total cost-benefit is unknown. For one, several CPU's for Scheme/LISP in past had hardware-accelerated garbage collection and/or a bunch of cores. Automatic, memory management and multicore are now mainstream due to perceived benefits. Works down to CPU in LISP machines.

Also, I've seen some of these benefits of Genera in modern stacks but I still don't have all of these capabilities:

Any jump out at you as particularly awesome for a developer OS?

Not only Lisp Machines, that was how many memory safe systems programming languages were done in the mainframe days.

Intel MPX, CHERI are just two modern approaches of reusing those ideas to tame C's memory issues.

Going back to FPGAs, I think function composition is very similar to digital circuit design, so FP concepts could be a very nice way to do GPGPU programming instead of the actual mainstream approaches. But it would require the GPU to be more FPGAs like.
