Ah, sorry. Totally missed the context of your comment.

Nanosystems is much more realistic.

Personally, I don't see the difference.

I've never understood why people feel that way. As far as I can tell, there is no evidence that consciousness is not able to be emulated by a machine.

You mean, like arrays of microscale acoustic generators? Maybe if the wavelength was small enough, one could manipulate singular molecules with nanometer precision? 3Ghz ultrasound at sea level has a wavelength of about 150 nm. Perhaps the

Microlens arrays seem very interesting! I haven't seen any that are very high resolution... Is that because they kill the resolution of the display they're placed upon (as well as technical problems with very small microlenses)? S

I'm not an expert, but I believe that's not how holographic displays would work with optical phased arrays. I believe a phased array can make it seem that light is being emitted from any point above the display (within the display

Phased arrays are very cool tech. Personally, I can't wait for visible-wavelength optical phased arrays to hit the mainstream (they're just now being implemented), since they'd enable tech like legitimately holographic displa

That line can be simplified to: fn compose<T, F: Fn(T)->T>(f1: F, f2: F) -> F {

Are you taking metformin/etc as well?

How are you getting that much without bankrupting yourself? It's extremely expensive, even in bulk powder form.

How many milligrams of NMN do you take each day?

Seems very maxwell's-demon-y to me.

You're right about the self-replicating part, that's probably very far away (and not necessary for this). But I think self-assembling nano-mechanisms are closer. We can already sort of do it with self-assembling dna mechanisms and

Oh no, it is extremely complex. However, every step along the path towards it provides benefits and, slowly but surely, researchers are moving forward. I think the field just needs more funding and more scientists dedicated towards it.
77.
by lachlan-sneff 7y ago
Well, you can laugh, but it's legitimate stuff. Right now, all we have is self-assembling dna structures, but there's a bootstrappable path towards "tiny robots".

"*nm" gates is just marketing speak. The transistors are actually still many 10s to 100s of nanometers across. Actual nanotech will allow for gates that are legitimately just a few nanometers across.
79.
by lachlan-sneff 7y ago
What perplexes me is that neither Intel, AMD, IBM, or any other company, as far as I can tell, is pursuing the bootstrapping path of self-assembling nanotech. Once someone does it, every other company is going to be left several orders of m

Gosh, you're right, somehow I never drew a connection between the two Epsteins.

The topic is quite controversial, but there is a path forward. There are several theoretical computing technologies that can get very close to the theoretical maximum allowed by physics (as well as being revisible), but we can't build

What use will quantum computers have? Can they do things other than factoring large numbers quickly?
