The general idea is to deliberately shape the geometry of spacetime to allow for effects such as faster-than-light travel (relative to another region of spacetime).
Einstein's field equations link geometry to matter and energy:
G_μν = 8πG/c⁴ · T_μν
Left side describes how spacetime curves (the metric tensor). Right side represents what's causing the curvature (the stress-energy tensor): mass, energy, momentum. The usual approach is: you specify T_μν (what matter is where) and solve for the resulting curvature. Metric engineering takes the backward approach. You pick the geometry you want first: e.g a bubble that carries its contents faster than light relative to the outside universe. Then you work out what T_μν would have to be to produce that geometry: what distribution of energy and stress the equations demand.
The classic example of spacetime metric engineering is the Alcubierre drive.
The limitation with this is that the required T_μν has negative energy density in some regions (the bubble walls) which violate some assumptions about how "reasonable" matter behaves. But Quantum Field theory allows such local regions of negative densities and we have created such regions in labs experimentally already (Casimir effect). We "just" don't know how to sustain the effect at bigger (atomic) distances.
Could you give an example of the value that only training a model can create but none of the rights-holder could? I feel like if you got a direct, instant communication channel to any of the rights-holder that created the content in the training set of those models, you'd get more value than what the LLM could ever give you on any specific subject.
All frontier models have been trained without any regards for IP protection laws. I don't see how anyone can argue in good faith that distillation is not fair game and does not ultimately "benefit humanity™"
Exactly. Imagine what would be possible after a billion year of technological evolution, heck even just 100'000 years. We already know that space time metric engineering is theoretically possible within our current understanding of physics, we don't have either the technology or access to energy density necessary to do it. And that's only within our limited understanding of how the universe works.
Neo4j is a great DB but their license price is egregious for enterprise customers. A few years ago I was involved in negotiating a contract for a small/medium size kubernetes deployment (think around 25 cores) and the annual price was more than the salary of a senior SWE full-time equivalent. See this page for an idea of their prices in 2018: https://blog.igovsol.com/2018/01/10/Neo4j-Commercial-Prices....
Even more so considering that most, if not all countries already have age-verification infrastructure in-place for selling alcohol and tobacco (and other goods). Why not piggy-back on this? Go to a kiosk/shop selling controlled goods, pay a small fee to the vendor to get a one-use verification code that attests your age.
Continue building useful models, tooling and products, market them to the people who could benefit and be realistic about their strength and weaknesses. Drop the messaging about job displacement, "transformative/dangerous AI", "significant disruptions" and "unprecedented abundance". They are the ones pushing and funding this narrative; just look at the phrasing in this announcement. And it's percolating down everywhere in the general public leading to AI psychosis.
They are proposing solutions to a hypothetical problem they are actively trying to manifest into reality to get more capital and funding.
That's what hypocritical about it. Not the development of the technology nor the effort to lobby for more regulations and policies.
The general discourse around AI could be much more sensible and pragmatic and lead to a more balanced, healthy rollout of the technology in society. But of course this means forfeiting at least part of the massive injection of capital in those companies and the ecosystem in the short-term.
I was not criticizing the technology in itself but the messaging and marketing around it. I agree with most of your points except perhaps the general sentiment outside of tech about AI. Most people I've talked to admire the technology but are genuinely scared or angry about the second-order effect of it on society. And I think, in part, it's because of the messaging, marketing and general psychosis about the technology that those companies are generating.
I see your point, but in this case we are not talking about disruption at the scale of a product category, vertical, or even an entire industry. AI companies are trying to disrupt entire sectors of the economy at the same time: knowledge work/white collar jobs, creative work (design, photo, video, ...), medical professions, etc.
They are recognizing themselves in their economic policy framework that the lowest level of unemployment potentially caused would be 5% (they also mention 10% and "unprecedented levels of unemployment").
I don't think there is a precedent for this claim. It's hard to take the "we're a force for good for humanity" message seriously in this context.
Interesting examples, thanks for the nice discussion!
I believe it goes deeper than the "logical proof" sense. It's a category mistake. Consciousness can never be "objectified".
About the readiness potential I'd argue that it's still happening in consciousness just not being registered by the mind of the participant. In the experiment "conscious decision" or "unconscious brain activities" are misnomers. Thoughts, decisions, memory, latent biases, etc. are processes of the mind not of consciousness.
Anesthesia and deep sleep are also useful scenarios to investigate. There is an interesting question to contemplate for those examples: are they an absence of experience or an experience of absence? I'd contend that it's the experience of the complete cessation of all workings of the mind and sense organs. But consciousness is still there. Otherwise how would you experience the transition from waking state to deep sleep/anesthesia and then back to waking?
> We are not seeking job displacement. We are working to prevent or minimize it. Some amount of displacement, though we cannot say how much, may be an intrinsic consequence of the technology, and our responsibility is to prepare for it and respond to it. That is what this framework is for.
> Whatever happens, we are on the side of people. We are trying to solve these problems. We take no satisfaction in contributing to them, and we are not working to make them more likely.
The cognitive dissonance/doublespeak/hypocrisy (pick one) is absolutely insane.
They are concurrently:
1. creating and marketing products that are explicitly trying to automate, if not entire professions, at least big parts of them
2. edicting grand policy plans to limit the impact of massive job displacement that their products might cause
3. directly funding and coordinating missionary-type activities ("it's for a greater cause") to evangelize and propagate said products in areas of the economy that are usually underfunded and where job security is already quite bad (non-profits, NGOs)
That might be too much of an assumption to make because of the binding problem. Imaging knowing absolutely everything there is to know - measurably, quantifiably, down to atomic/quantum states - about what happens when a human sees red but only having experienced a black and white world. Do you learn anything new when seeing a cherry for the first time? You experience red for the first time.
Measurement is third-person by definition, and consciousness is irreducibly first-person. So no instrument, however precise, can ever close that gap.
Consciousness/"the subject" is the raw material of reality. Matter, sensory inputs and mind are experienced as objects in consciousness not the other way around.
So in that sense "the subject" is exactly the same for the bat or the human.

There is no doubt that Graham is right in saying there is a formula to becoming a billionaire and that formula involves creating products that help your users in some way.
However this is very narrow, reductionist interpretation of AOC's comment. You need to put it into perspective of the massively increasing global wealth inequality.
In 2011, billionaires owned 4.5 trillion USD of wealth. Today, fifteen years later, it's 20.1 trillion USD. This amounts to about 20% of the entire planet's GDP. That means 0.000003% of humans capture 20% of the value globally created. The top 12 billionaires own more than 50% of the bottom half of humanity.
How can you sensibly argue that this is not exploitation?
This public-private drama will only get worse once the AI companies are public and most of the economy depend on their continued performance through their presence in everyone's retirement funds
The depravity of using a fun, uplifting game that targets kids and teenagers to train military drones boggles my mind. "The end justifies the means" continues to reign supreme
