"On the molecular scale, you find it's reasonable to have a machine that does a million steps per second, a mechanical system that works at computer speeds"
About this Quote
The phrase “reasonable to have a machine” is doing quiet rhetorical work. Reasonable compared to what: our clunky macroscopic machinery, or the cell’s own molecular motors that already run at furious rates? Drexler’s subtext is an implicit appeal to biology as a proof-of-concept: if ribosomes and ATP synthase can operate with breathtaking throughput, then “mechanical systems” at that scale don’t violate nature; they rhyme with it.
Then comes the cultural bridge: “computer speeds.” He’s not merely describing kinetics; he’s importing the prestige and inevitability of computing into materials science. In the late-20th-century imagination Drexler helped shape, the computer is the model technology: scalable, exponential, destiny-coded. Tying molecular machinery to that tempo hints at a future where manufacturing becomes programmable, where matter is as reconfigurable as software, and where the bottleneck is no longer physics but design. It’s an invitation and a warning: once you accept the speed, you’re already halfway to accepting the consequences.

| Source | Verified source: MD+DI (MPMN): Who’s Afraid of Nanotechnology? (K. Eric Drexler, 2004)
Evidence:
On the molecular scale, you find it's reasonable to have a machine that does a million steps per second, a mechanical system that works at computer speeds.. I was able to verify the quote verbatim in a primary-context publication that *quotes Drexler directly*: MD+DI Online’s reprint of an editor’s-page piece originally published in Medical Product Manufacturing News (MPMN), dated January 1, 2004. The quote appears as part of a longer Drexler quotation beginning “The really big difference is that what you make with a molecular machine can be completely precise…” and continuing through the ‘tuning fork’ analogy, then this sentence. The web page itself does not provide interview date/location details (i.e., when/where Drexler said it) or a transcript source. Some quote-aggregation sites attribute the sentence to Drexler’s 2013 book *Radical Abundance* (often citing p. 28), but those are not primary evidence, and I did not (in this search pass) locate a verifiable scan/searchable excerpt of the book page to confirm whether the sentence first appeared there or was quoted there from earlier remarks. Because the MD+DI/MPMN item is dated 2004, nine years before *Radical Abundance* (2013), it strongly suggests the quote circulated earlier than the book. To determine the *first* publication/spoken instance with high confidence, the next step would be to locate: (a) the original MPMN January 2004 print issue metadata and reporting notes, or (b) an earlier Drexler interview/transcript/lecture containing the same wording. |
