The original BASIC from Dartmouth was an intentionally limited dialect
of FORTRAN designed to introduce programming concepts to non-programmers
at an undergraduate level. While it has evolved into a usable
programming language in a couple of forms (see below) its original form
was totally unsuitable for use in professional settings. Despite that
fact, it was used as such. :)

I disagree. If you're going to teach Ruby as a first language, teach the
concepts first -- what is a class, what is an object, how does
object-oriented programming organize the world of data and programs, how
does one think in terms of objects, etc. Ruby is an object-oriented
language, and there's nothing in the whole object-oriented paradigm
that's "too deep" for a beginning programmer.

PICK and its variants are far from dying. There are even open-source
PICK emulations available now! As I noted above, the original BASIC was
not usable for professional programming. PICK BASIC, on the other hand,
is a well-crafted professional programming language and fits the PICK
operating system/database well.
I came to PICK after many years as a UNIX programmer, so the concepts
were somewhat strange. But I don't see your analogy between PICK and
Ruby at all. PICK is an OS integrated with a multivalue database and a
full-featured dialect of BASIC. Ruby is an object-oriented language that
can run on most operating systems and integrate with most databases.
