That's a really bad short article. Actual nanobot designs don't have "small metallic arms and claws", they are not made of metal but dense covalent macromolecules (usually "diamondoid", ie substituted diamond-like lattices), or some variation on graphene.

Proposals by Drexler, Freitas, Merkle and others in the field (as opposed to Sci-Fi BS) generally have been tested with the same ab initio quantum chemistry and molecular mechanics tools used by computational physical chemists to study and design real chemical reactions, later corroborated with experimental data.

Unfortunately, much of the introductory material is very dated, especially in style and presentation. Probably a good place to start for the technically inclined in Drexler's MIT dissertation, which is the basis for the book Nanosystems (one of the best sources), and can be freely downloaded here:

​

Some chapters of Nanosystems are also available online:

Then you can check out some videos on current experimental research at the Foresight website.

Freitas's and Merkle's websites look very dated but they contain some interesting links.

I hope that helps.

every decision Google is making is in regards to their legal liability and avoiding lawsuits. That’s it. They are at higher risk because of their size.

I don't understand this use case. Instead I would like a better Google Alert/News. You tell the bot I want to be informed about X and it collects the relevant webpages presenting them in a readable summaries format with links. Or compares prices of Y across webshops. Or a shopping assistant that fills in shopping baskets with the essential groceries on regular basis. But it shouldn't actually buy anything. I don't trust the bots enough yet.

This tool by SalesForce called ProGen is a LLM that can create new enyzmes from prompts: https://github.com/salesforce/progen

It never learned all the billions of possibilites of tertiary structures or all amino combos, it just interpolates after it learned a few millions from databases. The created / proposed "artifical enzymes" function like their biological counterparts while having derivative structure (molecular configuration) that dont appear in nature but do the same job. This is extremely impressive and I am sure AI will solve greater Nanotech problems by interpolation and pattern recombinations as well.

It may sound super simplistic but you dont need Nanorobots at all with this tool you could create Repair-Enzymes (Membranerepairase ;P etc.) and deliver them with Microrobots or Attached to Nanoparticles that can be controlled by magnetic fields (such tech already exists in cancer research, you bind drugs to iron particles or the drug / iron combo to a nanostructure and control their movement through the body with electromagnetic fields)

The 'shape of the solution' would look like hundreds of thousands, maybe millions of separate STM automated 'labs', in some larger research facility. (imagine a 1kmx1kmx1km cube or bigger). In parallel millions of experiments would run, with the goal of finding patterns of atoms to serve as each reliable machine part you need for a full nanoforge. And other experiments investigating the rules behind many possible nanostructures to develop a general model.
For every real experiment there are millions of simulated ones, where the AI system is systematically working on finding a full factory design that will be able to self replicate the entire factory, and to find a bootstrapping path of the least cost to build the minimum amount of nanomachinery the hard way, with all the rest of the parts made by partially functioning nanoassemblers.
"the hard way" means probably atom by atom, using STM tool heads to force each bond.

> A neural network learns a representation from the data. It literally scans ur work.

The neural network best know for this ability is the human brain. Aspiring artists and musicians scan many works during training which alter the parameters(synapses) of the neural net, allowing it to better recreate the training data or extrapolate from that data to create new and unique output. Sometimes, the parameters in the neural net are configured so precisely that it becomes possible for it to re-create copyrighted works with high precision. The ability to do this does not constitute copyright infringement. Copyright infringement only occurs if the recreation isn't properly attributed.

Agree. Around 2014 I read nanosystems and was pretty enthusiastic about the idea.

But as it turns out, the complexity of solving this problem is so large that human labs just won't be able to do it. Forget decades - I would argue if they couldn't use some form of AI at least as good as what has already been demonstrated, it may never get solved.

Companies can just let it generate some music for their stores, shows, movies, games etc. and artists stop making money completely besides live shows (which are already being taken over by holograms in Japan) while most people don't even notice. Unless it's made free and anyone can use it creatively and on the same level (not gonna happen)

And? You can still easily go to Hungary, and seeing as you claim to have been born in Romania, and therefore a citizen, you should be able to get through the Romanian border with relative ease

If you are such an individualist, then go and try to build a house entirely by yourself with resources that you obtained entirely by yourself without any assistance or trade whatsoever

You are nothing without the Collective, this is an objective fact

Yeah, I have no particular thoughts or strong feelings on nanobots (they would be great obviously but the medical revolution will happen with or without them), but the use of the word "never" makes him look like a tryhard at best and stupid at worst. Look at me I'm such a tuff skeptical badass I tell it like it iz, get bent you starry-eyed optimists holy shit I'm so fucking cool
