Okay, anyone else think this is too optimistic? Compare to the estimate from an actual experimentalist working with AFM:
>By the time I retire (~ 2040!), I’d really hope that we are at the point where we could simply instruct a computer to build nanostructures, and let the computer handle all the details – no human operator involvement required.

Constructing nanotech from scratch is basically a dead end. Groups which utilize existing organisms to perform tasks will always outcompete them.

Is there an enzyme that can make graphene sheets?

I do know biology is optimized to work at the nanoscale, and that biology will always be more efficient than diamondoid systems, but biology has different interests than we do. And if it can't synthesize graphene or diamond, then what do you do with it? Synthesize food?

Moreover, for hundreds of years people tried to stick wings to themselves and fly away, imitating the flight of birds. Nowadays, we can't even model the aerodynamics of bird flight, but we don't need to. We have planes that can go several times the speed of sound and even rockets.

I think the ultimate assembler, the true 'Universal Constructor', will be a seamless integration of biological solution-phase machines and diamondoid machine-phase machines, but unless you can generalize biology into something more, um, general purpose, I'll stick to atomic force microscopy->Silicon mechanosynthesis->Diamondoid mechanosynthesis.

a little fast, but I’d wouldn’t be too surprised with a very basic proof of concept demo by then (2020) ie: takes a longtime to replicate, needs a very particular lab environment, has limited onboard memory, and has poor cooperative skills.
I expect big things in macro scale automation over the next 10 years though, the cost threshold for useful vision systems is about to make dexterous flexible robots for factory work quite cheaper.

Well technically we've already sort of demonstrated this:

Pic quite related. But we can't really automate the process much.

It's the one below.

>The first experimental demonstration of purely mechanical positional synthesis, or mechanosynthesis, was achieved in 2003 by Oyabu and colleagues at Osaka University (Slide 5). They lowered a silicon AFM tip towards a cold silicon surface and pushed down on a single atom, mechanically breaking its bonds to neighboring atoms, allowing it to bind to the AFM tip. Images showed a hole where the atom had been. Pressing the tip back into the vacancy replaced the selected atom, this time using mechanical pressure to break the bond with the tip.

Change it to do what we want with it.

I was focusing on the first part of the concept demo. The rest referenced to a kinematic self-replicator and that's a bit further off.

ASSSEMMMMBLEEEEEEEEERRRRSS

By the way CCM, I think Drexler influenced the entirety of my previous school curriculum, since instead of Science or Technology, we had NANOTECHNOLOGY as a goddamn subject.

I think you complain about Australia too much. Also, when did you meet him and when and why did he go to your school?

[Inurdaes !V1sPhobos. No.3684098]

>>3684072
Our school shared the land with the university campus at which he works at.

He came in once in the first few weeks and there was a big assembly, and he did a rather lackluster presentation of nanotechnology, but that's to be expected seeing as he is explaining it to people who largely haven't heard of it yet as we just started there. Then he asked questions, and I got one of mine answered by him.

Also, I don't remember Drexler living in Australia.

I don't know man, that was over a year and a half ago. But I do remember it was a bit more in depth than the others. At the time I vaguely remember seeing him from somewhere, it wasn't until a few weeks later that I googled him and was, 'Holy shit, I talked to a slightly famous science person!'

And last time I checked it said he was working at that university. On a secondary Google though I cannot find that information, so I don't know anymore.

Also, Inurdaes, I'm going to have to ask for that comic you made the other day because I honestly can't find it.

[Colonel Coffee Mug !phJ7yIcs.Q No.3684186]

Wait, never mind, found it on Chromium's download list.

what is this device, does it work and i want one.

It's called a uniwheel, yes they work but you basically need to build it yourself.
