rfmcdpei, The Andorians working toward a solution does not negate the fact that the Genome was in itself the Deus Ex Machina. If it had been the Andorians who puzzled out the ancient knowledge rather than Bashir, it still would have qualified as a Deus Ex Machina.
Not really. Two years ago, in actual time and in in-universe time, the Shedai meta-genome was established as a very promising potential solution to Andorian fertility issues. A decade ago, the idea of introducing non-Andorian DNA into the Andorian gene pool to reverse Andorian demographic issues was introduced.
There is nothing sudden or abrupt in the particular solution to Andorian fertility issues. As I said above, the only thing that is sudden and abrupt is the sharp worsening in the situation. (Maybe this is a legacy of the attack by the Borg, who knows?)
It was a contrived all-powerful solution to a contrived all-encompassing doom.
The
Vanguard series did describe the Shedai meta-genome as an immensely powerful and capable technology that can be used to achieve remarkable things, yes. That's because it
is an immensely powerful and capable technology that can be used to achieve remarkable things.
If, in a science-fiction setting like
Star Trek's where advanced technologies are capable of remarkable achievements, you automatically define all such technologies--including technologies that had already been described, in some detail and at some time in the past--as deus ex machinae, you're going to find them everywhere. This may well be a problem for you, and not only because you're misunderstanding what's going on.
Granted, by using the political maneuvering of the Andorian rulers to withhold parts of the Genome, the drama was ratcheted up by TPTB. But the trickle of knowledge from the available godly pool of such does not negate the fact that it was a godly pool of knowledge that set everything right (in regards to the Andorian problem).
Radical technological breakthroughs were needed, sure. In the context of the universe, the ability to make use of the Shedai knowledge came about as a consequence of earlier, independent work done by Shar and others in making use of Yrythny DNA.
Absent the Shedai meta-genome, what would have happened? Perhaps the Yrythny DNA might have been made the basis of more effective treatments--it had achieved some success, just not enough. Quite possibly the Andorian species would have been set for extinction, regardless.
