- 原文: "Then, we had a series of three eras of advancement, in which machines rapidly gained areas of capabilities that far exceeded our own: * In the industrial revolution, mass manufacturing, or generally the ability to perform the exact same action millions of times * With calculators and computers, the ability to do mental tasks that can be defined via an analytic-philosophy-style logical definition (eg. computer code) * With LLMs, the ability to do mental tasks (and physical tasks, eg. already self-driving cars) that can be defined via a large set of examples But even after all three waves, at least today, there is still a large range of capabilities that remain unique to humans. A big question facing us is: is the LLM wave \"the real deal\", in the sense that, as they keep getting better, they will eventually cover either all missing capabilities, or at least enough capabilities that the rest can be worked around, or are LLMs simply a continuation of the same pattern, and it will take some fourth or fifth wave to go the rest of the way?"

- 原文: Anything is possible. It’s the probabilities that matter. Everything must be weighed in terms of its likelihood and prioritized. People who can accurately sort probabilities from possibilities are generally strong at “practical thinking”; they’re the opposite of the “philosopher” types who tend to get lost in clouds of possibilities.

- 原文: "But here we get to the thing that will confound looking at human and machine as separate units: the possibility of deeper and deeper integration between human and machine. This is the strand of technology that includes: computers being able to work much more symbiotically with us, picking up on all kinds of conscious and sub-conscious signals we release as an interface, brain-computer interfaces, computer-assisted telepathy that helps multiple people better understand each other and work together. The ultimate end is erasing the binary divide between human and machine and opening up any position on that spectrum. On one end, you sitting at a laptop terminal; on the other end, mind uploading, and also everything in between. The hope is that deeply integrated human + machine will outperform separated human + machine, and that this will remain the case all the way up to the technological ceiling. This is the best \"far-future AI outcome that I actually like\" that I can come up with: * We preserve global political and economic pluralism (no single company or government dominates) all the way up to the technological ceiling. * We humans each get the ability to either take technological upgrades to ourselves, and explore the universe at a level competitive with \"pure\" machines, or stay as we are, and get some ability to act in the world through having a bot listen to our instructions. * Most of Earth will probably become a highly-regulated nature preserve where anyone can continue living the kind of life they have now (without the pains and annoyances; most challenge will be healthy \"good challenge\"), and if you want to do more crazy things, you go to space. Make no mistake - this is a ride through a narrow corridor. Things could go off the rails in one of several different ways: AI-on-its-own could get too powerful relative to the alternatives; one country or one company could gain decisive advantage and decide to lock it in permanently, powerful technological ways of destroying each other could cause incalculable harm, or the human + machine integration approach itself ends up preserving not enough of our humanity, and so it ends up being \"just another way to make powerful bots\". For these reasons, I wish that we can ride through the narrow corridor at 60 kph and not 200 kph, which is why I feel warmly toward \"slowdown\" / \"pause\" proposals (including \"give us a chance to hit the brakes\" ideas like mutually assured compute destruction (as in AI 2040, also previously Dan Hendrycks, and others)). My ideal world is actually one where (i) open weights wins, and (ii) Dean Ball turns out to be completely right that open weights is decelerationist because it deters capex in frontier models [though it will enable more capex in peripherals and applications], because then we get slowdown without any of the downsides of doing it through heavier-handed political means. But also I don't think we should count on the world to naturally give us \"convenient\" laws of economics and physics. We do have some degree of agency over the laws of politics, plenty of ways to change incentives without putting a king in charge, and we should exercise that.

- 原文: "What do the \"last days of human dominance\" look like? (This is assuming that a permanent global stop to AI development does not happen) First, recall my definition of AGI: AGI is AI that is powerful enough that if you were to upload it into robot bodies, and all humans suddenly disappeared, it would be able to independently continue civilization. Why this definition, and not something simpler like \"AI that can do 90% of economic tasks at median human level\"? Because I think this definition captures the core thing that makes AGI \"not just a tool\", that make it uniquely powerful and unsettling: In a \"on-the-ground\" near-term sense, it means that no specific single job is truly safe from automation. Some jobs might have temporary human advantage, but if they needed to, AIs could eventually figure their way around anything. But also in a more high-level megapolitical sense, once we have AGI, the fact that it's humans who are masters of the Earth, and not robots, becomes a mere historical contingency (we have the property rights and the master keys to the guns, bots don't), and not an inherent result of bots having any fundamental limitation that we do not have. Even if technology were to advance no further, over centuries and millennia as the world continues to do a random walk constantly restructuring its political organization, there is no guarantee that eventually bots would not be on top - and then win permanently due to their greater ability to mass produce themselves. So AGI, defined as I define it, is a \"point of no return\" that merits great caution.
