Release the cranky!
Imagine that all reporting on astronomy and astrophysics covered only those research findings that had been generated by mycologists, geologists, and specialists in Victorian-era American literature.
That's what it's like to read about linguistics (inter alia) in even 'serious' popular science journals.
So I don't hate this Slate blurb as much as I was prepared to at first, not at all. Yes, it's disappointing that it leans on known crowd-pleasers of negligible interest/credibility among linguists, coming from an author whom I don't know but assume has formal postgraduate training in some field of contemporary linguistics. I don't get the impression the author even pretended to put any effort into whipping this one out. (And I'd beg to disagree with robject about the connotation or denotation of "epiphenomena" ;p -- but then I shared a lot of teachers and mentors with Terry Deacon, and am generally a fan of his work).
W/r/t Chomsky, I thought he'd pretty much dropped Universal Grammar proper by the early 1980s in favor of things like the much more appealing
Governess & Bondage Theory -- but then another feature of reading linguistics reportage and 'science education' is that when it does manage to cite ideas of actual linguists, it's usually a solid academic generation (~15 years, say) behind current events, and is often found quite happy paddling around in work that was being superseded a solid two
human generations ago.
Here's what I like about this piece:
Along this line of thinking, if aliens have something we recognize as language in the first place, then it's probably going to be a language much like any other, with arbitrary association between symbols and meanings, discrete units ("words"), the ability to talk about new things and things that aren't there, and so on.
This is the same basic argument that many exobiologists use for extraterrestrial life: Alien life has to be a least a little bit like what we're used to or we'd never recognize it for what it is.
This. More narrowly than the possibility of recognizing 'alien life' -- I'll leave that to biologists (anyway, not being a computer scientist or a philosopher, my thoughts on that subject aren't worthy of airing) -- I find it generally unlikely that humans will be able to recognize alien intelligence or its communication, much less 'decode' it.
That's why, as someone from the squishy thinky talky sciences, I've always taken Traveller to clearly be loose, light science fantasy. There's nothing 'hard SF' about it from my (lowly, unworthy, contemptible) perspective.
And, FTR, I like it a lot.
EDIT: Come to think of it, the Slate piece doesn't name-drop either Joseph Greenberg (& co.) OR Jared Diamond. It's actually AWESOME!!!
