You can argue that Emacs is a "Lisp machine", in that it's an environment you could conceivably think of as a kind of virtual "machine" in which you can run a particular Lisp (although arguably Elisp isn't what most people mean by Lisp), but this is about Lisp Machines[0], which are very specific historical computers.

I hope it would go without saying to anyone looking to adopt Lisp that this is for historical interest* only and you should instead install a modern Lisp like SBCL or what have you.

* (nd IMO its the sort of historical interest that indeed belongs on the front page of HN)

You're right that "Lisp Machines" refer to a very peculiar point in time, available to only a very small number of people.

The article even mentions: > This was all accurate as of around 2018, but please be aware that things may have changed since then!

There's no reason this should appear on the frontpage of a "news" site.

Based on the age of your account, you're new here, so...for better or worse, things that aren't "News" regularly are popular on Hacker News. Even if it's not new, it's can still be new to one of the lucky 10,000.
