Even if you (or anyone, for that matter) might be comfortable with that, I think you'd find that a lot of patients wouldn't be.

jashephe | 8 years ago | on: Dustin Moskovitz pours funds into high-risk research
A growing number of people have voiced objections to the burdens of the FDA's efficacy testing requirements, but it's worth at least thinking about why they're in place. The main issue is that "safety" in the context of pharmaceuticals doesn't mean "perfectly safe" or even "non-lethal" — it really means, "safe enough, given the benefits". Side effects of a chemotherapy drug that can completely eliminate a tumor, for instance, could be acceptably substantial, because it cures an otherwise terminal illness. Side effects of a drug mildly lowering cholesterol levels, by contrast, must be strictly limited, because many Americans may take such a drug for much of their adult lives, sometimes in combination if the effects of a single drug are too weak.
It's hard to know if the benefits outweigh the risks if you don't know what the benefits are. Obviously, this efficacy testing carries a huge time and monetary burden, but without it, contextualizing acceptable risk would be difficult, if not impossible.

More importantly, "near-infinite" lifespans reduce the efficacy of natural selection — longer-living organisms evolve at a slower rate. While, perhaps, unappealing, the culling of species members well past reproductive age is necessary to allow for more resources and potential for competition and selection in their offspring. And humans are certainly still undergoing natural selection in many arenas; just look at sickle cell trait [5] or or CCR5-Δ32 [6].
Death is a feature, not a bug.

While it's certainly true that it's hard to determine the function of a DNA sequence from scratch, it's considerably easier to compare that sequence (or the sequence of the translated polypeptide) to other homologous sequences to see if it matches something dangerous.
I previously worked in a lab that studied Bacillus anthracis, and we had a bit of trouble getting a major gene synthesis company [1] to produce a plasmid with a variant of atxA [2], and atxA isn't even a toxin, it's just a transcriptional regulator. We presumed that they just BLASTed [3] the sequence we gave them and threw up a red flag when it matched anthracis. So this sort of sequence-checking already occurs.

I was under the impression that stuxnet had a demonstrably negative impact on the capacity of the Iranian nuclear program to enrich uranium. Of course, there's a whole different argument on whether or not that's in support of "terror".

It's a pity that I can't source this specifically, but I vaguely remember reading in either James Bamford's "The Shadow Factory" [1] or his "Body of Secrets" [2] that the NSA once leased an entire office building that had been built near the edge of Fort Meade, simply because the top floors could see onto the campus.

Of course, my inner cynic is leaning pretty heavily towards Occam's razor for this one.
