Would love to see the FSD Scaling Law, as it’s the only physical data flywheel at planetary scale. What’s the “emergent ability threshold” for model/data size?

[Jim Fan @DrJimFan]

I'm observing a mini Moravec's paradox within robotics: gymnastics that are difficult for humans are much easier for robots than "unsexy" tasks like cooking, cleaning, and assembling. It leads to a cognitive dissonance for people outside the field, "so, robots can parkour & breakdance, but why can't they take care of my dog?" Trust me, I got asked by my parents about this more than you think ...

The "Robot Moravec's paradox" also creates the illusion that physical AI capabilities are way more advanced than they truly are. I'm not singling out Unitree, as it applies widely to all recent acrobatic demos in the industry. Here's a simple test: if you set up a wall in front of the side-flipping robot, it will slam into it at full force and make a spectacle. Because it's just overfitting that single reference motion, without any awareness of the surroundings.

Here's why the paradox exists: it's much easier to train a "blind gymnast" than a robot that sees and manipulates. The former can be solved entirely in simulation and transferred zero-shot to the real world, while the latter demands extremely realistic rendering, contact physics, and messy real-world object dynamics - none of which can be simulated well.

Imagine you can train LLMs not from the internet, but from a purely hand-crafted text console game. Roboticists got lucky. We happen to live in a world where accelerated physics engines are so good that we can get away with impressive acrobatics using literally zero real data. But we haven't yet discovered the same cheat code for general dexterity.

Till then, we'll still get questioned by our confused parents.

互联网真是有很多碎片记忆。把过去的twitter看完一遍，很多事跟记忆中有差别啊，不过也没什么矫情的好感慨。毕竟年纪大，没时间感怀���。

@zygqd 经济成本可以接受的话，出国当然会获得更丰富的体验。

@unique 不要说佩服，我很忐忑。我素危机强迫症患者，想的多，做的少。

[大吉 @DorisQ]

虽然他们都说我年纪小，没事，还能折腾。但是我总想着两年啊，工作都两年多了我的成长还这么迟缓。

@unique 我记得没有直接送车子的福利，就是叉叉主管可以配车，叉叉员工在付款上可以得到一定的实惠酱紫。

对自己的工作现状满意为止了再走，不要把完全的缺点带到下一个地方。

@zygqd 风俗不同的地方我都喜欢。

@zygqd 1.我觉得换个类型的公司，从媒体到企业，可以让你拥有��丰富的视角。2.广宣有个同��是从媒体跳过来负责媒介，做的并不开心，部门内斗比较严重，处处受人压制。3.我认识的会做销售的人说做销售至少要做两年，你才能掌握它的精髓。4.关键还是取决于机会。

@zygqd 我们这广宣的成天想着挪预算給媒体费用，大把大把的回扣。

@vian527 我相信他还没准备好去接受一段稳定的恋情，这不是你的原因。

[大吉 @DorisQ]

@teresall 我跟我妈现在也这样，无可奈何。

@vian527 那是我们公司内部原因才多放的啦
