A Quote by K. Eric Drexler

Protein engineering is a technology of molecular machines - of molecular machines that are part of replicators - and so it comes from an area that already raises some of the issues that nanotechnology will raise.
If you search the scientific literature on evolution, and if you focus your search on the question of how molecular machines - the basis of life - developed, you find an eerie and complete silence. The complexity of life's foundation has paralyzed science's attempt to account for it; molecular machines raise an as-yet-impenetrable barrier to Darwinism's universal reach.
A religious college in Cairo is considering issues of nanotechnology: If replicators are used to prepare a copy of a strip of bacon, right down to the molecular level, but without it ever being part of a pig, how is it to be treated?
In many biological structures proteins are simply components of larger molecular machines.
Essentially, every technology you have ever heard of, where electrons move from here to there, has the potential to be revolutionized by the availability of molecular wires made up of carbon. Organic chemists will start building devices. Molecular electronics could become reality.
A molecular manufacturing technology will let us build molecular surgical tools, and those tools will, for the first time, let us directly address the problems at the very root level.
We have to accept that we are just machines. That's certainly what modern molecular biology says about us.
We have always underestimated the cell...The entire cell can be viewed as a factory that contains an elaborate network of interlocking assembly lines, each of which is composed of a set of large protein machines...Why do we call [them] machines? Precisely because, like machines invented by humans to deal efficiently with the macroscopic world, these protein assemblies contain highly coordinated moving parts.
I wanted to rewrite the code of life, to make new molecular machines that would solve human problems.
We are built as gene machines and cultured as meme machines, but we have the power to turn against our creators. We, alone on earth, can rebel against the tyranny of the selfish replicators.
Molecular chirality plays a key role in science and technology. In particular, life depends on molecular chirality in that many biological functions are inherently dissymmetric.
The reality of our century is technology: the invention, construction and maintenance of machines. To be a user of machines is to be of the spirit of this century. Machines have replaced the transcendental spiritualism of past eras.
By the time of the Singularity, there won't be a distinction between humans and technology. This is not because humans will have become what we think of as machines today, but rather machines will have progressed to be like humans and beyond. Technology will be the metaphorical opposable thumb that enables our next step in evolution.
But while doing that I'd been following a variety of fields in science and technology, including the work in molecular biology, genetic engineering, and so forth.
I had been impressed by the fact that biological systems were based on molecular machines and that we were learning to design and build these sorts of things.
After realizing that we would eventually be able to build molecular machines that could arrange atoms to form virtually any pattern that we wanted, I saw that an awful lot of consequences followed from that.
When ATM machines came out and people were prosecuted for robbing ATM machines, I don't think anybody thought the banks were against technology because they didn't want their ATM machines lifted.
