I build stuff.

@yongfook n a world where AI is shifting scarcity every day, nothing is the definite real moat.

The real moat is having a happy family with a healthy body.

My entire X feed is

- software is dead
- distribution is the moat now

Original thought is dead.

@herval @quxiaoyin "a lot of people find appealing" verifiable but long feedback loop.

"deeper than average understanding" needs definition or measure.

[JZ Junyu Zheng @jz_build]

@Huxpro Bros in frontier labs are saying even model inference acceleration is solved. I consider that to be the most backend-backend job.

So no, there is no real moat. Earn your last penny while you still can.

@SamVale29 gold digging.

@AlanShao111 宝二爷

[JZ Junyu Zheng @jz_build]

@theo cool.

Legacy eng team spends a month making a "steer" feature in their chat bot, only to be killed by the next model update.

[JZ Junyu Zheng @jz_build]

Agreed.

If you're worried about slops, then your loop isn't built right. That's the equivalent of asking a blind-folded engineer to build something and wishing it magically work.

@wheresryan22 @rauchg lolll didn't prepare your credit card for this?

[JZ Junyu Zheng @jz_build]

I used to think that AI eval is something human need to curate, but now it seems that AI writes it better and faster than me. In which case, what is it I can still do besides just saying "Hey Claude/Codex please build an eval for this AI agent?"

@dabit3 I like your "find opportunities in the chaos and disruption" argument, but clearly chaos and disruption is not the end game.

Software is dead.

@MaxForAI API cost比subscription贵太多了。真的能撑多久吗？

[JZ Junyu Zheng @jz_build]

@imjustnewatai @thsottiaux You're a born babysitter. Nice.

[JZ Junyu Zheng @jz_build]

@dotey 5000人不光是内部模型，还有内部新出的harness和architecture吧。哪怕是同一个模型，在frontier一点的地方，可能也会看到一些更离谱的应用方式。

@realEstateTrent @patrickc +1

Patrick’s written it well. But too well that my ASD-STE100 brain cannot comprehend.

[JZ Junyu Zheng @jz_build]

A technology whose externality reaches the whole world yet the governance can never be global - pacing AI has no practical chance.

Think about the Cold War.

[OpenAI @OpenAI]

At the core of our mission is working through how to ensure increasingly powerful AI benefits everyone.

We believe that, at some point in the future, AI acceleration for frontier model development may be so high that the world will need to pace the rate of AI advancement.

We hope to contribute to work led by the U.S. government, alongside other labs and the open-source community, to develop the tools and mechanisms that could make that possible.
