I haven't had a chance to read the linked article yet, but it looks
like it could be VERY relevant to the topic of abiogenesis. Also to
the question of why and how an RNA based intelligent species would
develop nanotechnology to produce a large range of proteins. Even
trial and error, it seems, could produce some fairly useful proteins
that they could then incorporate into their own genomes, and more
especially (due to fewer ethical concerns) some select micro-
organisms.
They might keep a number of altered micro-organisms under heavy guard,
like the smallpox virus is now kept under heavy guard. They could
then go on to modify them still further, and perhaps within a century
they could design an organism that has enough polypeptides coded into
its mRNA to realize a complete "protein takeover".
These organisms could then be ready for sending in space probes for
seeding suitable planets, among them the earth of ca. 3.9 billion
years ago.

That's the guy. Works at the Institute for Mopping Floors Really Clean.

What I find interesting about this is that there is, as it were, an
enormous range of cryptic functions in any set of RNAs. This has at
least two implications:
1. You do not need intelligence to "find" function in such cases
2. Any intelligence would be unable to ensure that their chosen function
would be the one employed in a novel environment.

Sucks to be you, doesn't it?
I started following the NG at the tail end of the "good old days."
While mostly lurking in 1998-2001 I spent more time with the archive,
including the "Jargon file" which has lots of insider references. Such
as the "Kalki syndrome" which refers to a TO regular (denier) from the
90s who, like Nyikos has returned recently.

It makes me feel old to hear of someone I knew as a graduate student
(it seems like just a couple of years ago) having an endowed
professorship.

Yeah? Well, I'll see your deaddog and raise you an ocelot, a live,
wild specimen of which was spotted in the Huachuca Mountains of
southern Arizona recently:

Yabbut the ocelot never posted to t.o
Me, I don't like many things. And the things I like, I don't like
liking them.

On the internet no one knows your an ocelot. Opps!

The Chinese pretend their goods are good and we pretend our money
is good, or is it the reverse?
Actually, the ocelots are usually spotted whenever they post to the
internet.
I ocelot, but not in public.

I'd add 3) That it is surprising that the phase space occupied by
biologically active proteins is relatively so small.

Ah, but you do need intelligence to CHOOSE the functions that are
"desirable" from your point of view, and to match them with what you
observe the catalysts to be producing.
The big question in all this is whether the functions can be enhanced
to the degree necessary for the production of a "successful"
organism. An intelligence, proceeding according to a desired goal
(like pictures that look like those of insects, in a famous
"experiment" touted by Dawkins in _The Blind Watchmaker_) should be
able to get the desired effects, given a couple of centuries. Whether
a natural, unguided environment can be expected to produce such a
thing within a billion or so years is another matter.

Unless they design the organism themselves, and release it in the
appropriate environment.

Didn't you mean to say "so large"? If not, you are suggesting that my
standing challenge is going to be hard to meet, even with me setting
the bar so low: find a scenario for getting from something like the
thioester world of Christian de Duve to the first prokaryotes.
