taste （品位/灵性）是一种超越了个人爱好，可复利，可长期实践的个人判断系统。能够帮助你在无意识中对什么是好的 什么是对的 、值得的做出判断。
并且最关键的是 品味是可以后天锻炼的。

Taste is how your background introduces itself quietly.

It shows up in what you invest in,
how you make decisions,
and the way you speak and act.

A startup idea that only works if there are already a significant number of people using it is not a valid startup idea. There has to be some subset of users who need what you're making so desperately that they'll use it even if no one else is.

使用工具的根本目的是提高效率。而提升效率的根本目的是为了做大蛋糕、创造新价值，让不可能成为可能。

@elonmusk Product create core value. Brand can amplify core value, but it cannot create from nothing.

生产范式越是剧烈变化，个体层面上 越是不应该只追逐单一热点。热点提供的是增长率 确保你能上桌，而护城河则决定了下桌的时候你能剩下什么。

但是聊这些事的大前提是 必须承认自己的无知，剧变期 太多变量了 很多时候并不知道哪条护城河会活下来，因此保留optionality（便宜的、可叠加的多个小赌注），有时候会比single deep moat 更好。并且这些小机会有时候会产生奇妙的化学反应。

$GOOGL Gemini 3.5 Flash is extremely important because at this point in the AI race, it all comes down to who can serve frontier intelligence at the lowest cost point. Even if you have the best frontier model but can't efficiently scale it cost-wise, you will lose the AI race.

$GOOGL has now put 3.5. Flash in $GOOGL Search (AI overviews, AI mode, YT, Spark, etc.), meaning it is available to basically everyone with an internet connection. Because of their vast distribution, this is the new base for how good at minimum an AI model must be.

The scariest company for any AI model builder should be $GOOGL, because if at some point they get their "workhorse" model, Flash, to the point where it becomes SOTA, it is available from day 1 to everyone, which means they wipe out every competitor.

Personal update: I've joined Anthropic. I think the next few years at the frontier of LLMs will be especially formative. I am very excited to join the team here and get back to R&D. I remain deeply passionate about education and plan to resume my work on it in time.

最近一个感悟：不要自己把思路禁锢住。坦然接受自己擅长的部分，也接受自己暂时无能为力的部分。不要总是闭门造车，多去了解不同的方向，和不同的人聊天。

很多好想法，其实都是聊出来的，networking 出来的。不要害怕未知。特别是在 long-term game 的前提下，大部分人其实是愿意连接和分享的。

尤其是那些过去的弱链接，coffee chat之后再做recap 的收益往往很高。

Greg Abel already sounds like a great CEO, and he clearly has a sense of humor too.
There was a question from the audience asking whether he supports Canada or the U.S. in hockey. He gave a very diplomatic answer: because Connor McDavid is from Edmonton, and he is from Edmonton as well, he supports the Canadian men’s team and the U.S. women’s team, even though his own family has different opinions 😂

@Svwang1 AI 出的活，核心判断力有时候会有问题。自己立不住。也能理解，AI做的判断本质上是选了个平均值。
