Just so that I'm clear on what you're asserting...

A few questions.
Aren't these assertions mildly incompatible?
I'd assumed that your thin-print method was what you were referring to as machine phase; though incremental the implication, I thought, was a gradually-automated and increasingly "smart" industrial process improvement. No? Re: that process, that's the one for which I think you're underestimating the costs (but overestimating the timeframes given adequate funding, which is not in fact practical as we've already agreed.)
If we can't engineer harvestable species or clusters and won't be able to until we're pretty far down the road, then how do we do this:

(I interpreted your statement as: pass through machine phase to an advanced biocentric method. Apparently that's not what you meant? That was the idea I was thinking was particularly interesting... seems to me the phase-cycle most likely goes: industrial processes -> bio-bootstrap -> advanced machines...)

What year / dollars are you assuming, here? (You might argue that this is somewhat unitless... also, begs the definition of "tanks.") I think it's a lowball, but would probably split the difference between this and my $200 / barrel, in 2009 dollars.)
Re: "a war." "A?" At least. That's the closest thing I've heard in this whole conversation, from anyone, me included, to certainty assuming we fall too far into the gap. Arguably, already happening.
