【令人震惊的数字】通用汽车用 AI 将 CFD/FEA 工程仿真从 15 小时缩短至 1 分钟——900 倍加速。这个数字让所有关于「AI 提升 10-20% 效率」的讨论相形见绌：当一个工程师原本需要等待 15 小时才能看到仿真结果，现在只需 1 分钟，他在同样的时间内可以迭代 900 次而不是 1 次。这是「设计速度极限」的系统性重置——汽车研发周期将从「年」压缩到「周」。

NLA能够检测到模型在评估中未明确表达出的意识，而在实际用户使用中这种意识出现的频率极低。

将物理模拟算法与CSS动画结合，创造出更自然的动画效果，这代表了设计工具与物理模拟的前沿融合。这种技术可能成为未来UI动画的标准，提供更接近物理世界的设计体验。

传统电磁仿真工具的致命缺陷在于“不可累积性”。每一次数值求解都是从零开始的暴力计算，专家的隐性知识被白白浪费。引入基础模型的核心逻辑，正是将沉淀在人脑中的机构知识内化为模型表征，实现知识的复利增长，突破人类直觉和算力双重瓶颈。

大多数人可能认为3D生成只是世界模型的一个可选组件，但作者强调3D生成对实现真实物理模拟至关重要，这挑战了当前AI研究中2D视觉处理的主流趋势。这一观点暗示未来世界模型研究必须重视3D空间理解，而不仅仅是2D图像处理。

• Quote: Michael Levin
  • Sometimes people ask me "is it possible that we're living in a simulation?
    • and and if you think about it it's not just possible it's guaranteed.
  • There's no other way it could possibly be
  • If you think about what is the opposite of that
    • the opposite of that is that you somehow have a physically embodied cognitive structure that
      • is able to,
      • is not limited in its sensory perceptions
      • is not limited in the amount of memory and computations
  • All of us are limited beings
  • All of us evolved under constraints of
    • time
    • energy and
    • everything else -We see a tiny, little, narrow slit in the electromagnetic spectrum
  • We have a few other things
    • like chemical senses of things that are right there on your tongue and
    • on your fingers and so on
    • we have a little bit of memory
    • we have this wet squishy substrate
      • that's very error prone and
      • needs to be constantly maintained
    • and all our memories have to be the actively rewritten
    • We were evolved under specific pressures under those conditions
  • Who could possibly think that that we are not living in some sort of very specific representation of reality
    • that is limited in many ways
  • That's not to say
    • it isn't adaptive and that
    • Donald Hoffman would say that in many ways it is completely wrong
  • I I think there's probably some truth to that
    • but in other ways I think the the big lesson from all this is that
    • we are all a brain and a vat
  • Of course we are a brain sitting inside this thing that gives us various stimuli
  • We try to make the best sense of it that we can and creatures will adapt to
  • This is why you can do
    • sensory substitution and
    • sensory augmentation and why
    • you can have neurons in the dish that play Pong
  • but these systems will try to make sense of whatever world they're given
    • in whatever configuration they have and we do the same
  • So yeah absolutely it's an illusion
    • but it's not an illusion in the sense that there is some other way to have perfect direct perception of some underlying reality
  • When we say it's an illusion or a simulation
    • It just acknowledges the fact that we are finite limited beings
    • whose job it is to make the best sense we can
    • using the hardware that we have
    • of what's been going on up until now and what we predict is going to be going on
  • I don't know of another story that could possibly make sense

• comment

• good observation, that's why I have always felt strange about the simulation hypothesis. If it's a simulation, it automatically assumes, there is something which is real and not a simulation.

  • See Donald Hoffman's Information theory and contention that we live in a simulation. Does it also come with the same implicit materialist assumption?
  • The nagging thing about the simulation theories is it is also a narrative that posits an unknowable reality beyond which we can never access - a rendition of the narrative that we only ever have access to the shadows in Plato's cave.

• comment
  • I agreed with a lot of what he said up to now. In fact, he does a rather good presentation summarizing the contemporary problems we face and emphasizing the acceleration of change in all human spheres, giving rise to our current polycrisis
  • I agree that the mythos of materialism needs to be seriously explored and other perspectives may give us new salient insights, but I don't think it's so obvious that the theory that we are living in a simulation.
    • and quantum gravity theory a highly abstract cultural artefact being used to prove that
  • is going to be the panacea to create a compelling new mythos..
  • If technology alone is insufficient as he earlier claimed, then quantum gravity theory, as part of the entangled STEMS nexus is part of that techno-complex that is insufficient.
  • This claim will have to be proven true by strong and compelling evidence that receives mass acceptance. Without that, it becomes an unjustified claim and the complexity of it will elude most people.

• comment
  • Klee Irwin is a controversial figure. His claims need to be interrogated quite critically.
  • His first doom and gloom section is accurate meta presentation, but his claims on advanced physics have been questioned by a number of critics.

in the 1960s the US military had reports on gender bias wrt simulator sickness. (Such simulators would likely have been more of the physical (rotation, speeds etc.) than virtual (screens / vr))

Pre-service teachers can benefit from the use of simulations that reproduce classroom environments, student behaviors and profiles, and academic outcomes to guide their craft as educators. In this text, simSchool is briefly evaluated by student teachers to determine its usefulness. While the study had significant limitations of volunteer test subjects in a one-time usage of the tool, simSchool still was given some high marks for it's purpose and realistic depiction of student profiles and classroom environment. Finding suggest simulations like simSchool can continue to improve and with long-term use, would be effective at developing skills for educators. Rating: 8/10

In the text by Jennifer Herseim, virtual reality (VR) is identified as a tool to help with teacher training. Teachers can embark on a learning process in a secure environment with a diverse set of student avatars operated in part, by a real individual. Staff can explore their teaching methods and styles with recorded and measured skills and responses for future review and reflection. Rating 7/10

This is interesting!

So there's more to it than building things and surviving? A student who plays minecraft told me today that he thinks you actually do learn what you are simulating in the game. "Like when you build a garden, you learn how to farm," he told me. Hmmmm.
