I cannot help but find this discussion of "dead languages" fascinating,
particularly in the context of a Classic Computer mailing list.
A language is not dead simply because somebody has not heard of it. Nor is
it dead because the latest Python, JavaScript, or Ruby programmer has never
encountered it. By that measure, half of computing history would vanish
every few years.
The whole reason groups like this exist is because there are still people
actively using, studying, teaching, repairing, and preserving these
technologies. Around the world there are enthusiasts rebuilding Apollo
guidance computer rope memory, reproducing DSKYs, restoring S100 and STD
bus systems, maintaining FORTH environments, repairing PDPs, and keeping
countless other pieces of computing history operational. Many of these
systems are not museum exhibits. They are running, being developed, and
teaching new generations how computing worked before abstraction layers hid
all the interesting parts.
Perhaps a better definition of a dead language is one for which there is
nobody left who can read it, write it, teach it, or care about it. By that
standard, many of the languages being discussed here are very much alive.
They may not be fashionable, they may not appear in job advertisements, and
they may not be taught at university, but they are still being used by
communities that value them.
If anything, the existence of this mailing list is evidence against the
idea that these languages are dead. We are quite literally the people
keeping the knowledge alive and passing it on to those who come after us.
Dead? Maybe. Mostly dead? Certainly not.

For a languageto get CALLED "dead" does not
require any of those objective
criteria. It gets called dead if somebody hasn't heard anything about it
in a long time.
Somebody who hasn't heard anything about mainframes in years thinks that
mainframes are dead.
Somebody who hasn't heard anything about COBOL in years thinks that
COBOL is dead.
Most stuff being called "dead" is not by objective criteria; it just
hasn't been talked about much lately. Among THAT person's social circle.
I agree with most of your objective criteria, except lack of recent
update. While it is true that most active languages get frequent updates,
but that isn't requisite for not being dead.
Should we say that a person is dead if they haven't been to the doctor in
10 (25, 50) years? It would call for a wellness check, but hardly an
assumption of demise.
Recently some AI generated facebook post recounted Cliff Stoll's famous
tracking down of intruders. The same article said that Cliff died in May
2024. Cliff says that the news of his death is slightly exaggerated.
