One step closer to 4-8x faster Ethereum finality!
It took some time and lots of tokens, but we now have a formally verified proposal for a decoupled consensus protocol in I* (a future Ethereum upgrade)! Not yet a full spec (up next), but it includes all the key consensus-relevant details to become one.
Since Ethereum aspires to be live without most of the stake online, the protocol involves many more components than a normal BFT protocol, and its correctness involves much more than standard safety and liveness. Those nuanced properties are now verified!
What's more, I came away convinced that all protocol design will involve AI-assisted Formal Verification in the future, both for correctness and iteration speed.
The work wasn't limited to just:
Design the protocol -> Formally verify it
Instead, the loop became more like:
Design -> Formal Model -> Find exactly what breaks and why -> Redesign it.
For a fairly complicated protocol like this one, I think having the Lean model be part of the design loop played a big role in accelerating the process.
A future with agents paired with formal models is a superpower for Ethereum development, because they can then use those models to find exactly where an argument breaks down, formalize counterexamples, test proposed fixes, iterate on the protocol.
Many details that would slip under the radar when asking agents (and indeed, humans) can now be specified exactly and checked by the Lean kernel. This then forces agents to be more precise and lets them make verifiable progress on their own. It's been incredible to see this play out, seeing agents find gaps and propose protocol changes to fix them.
In other words, autoresearch can speed up protocol design, formal verification is here to stay, and Ethereum Finality will get faster.

Grok 4.5 is the truth seeking leader that other AIs can aspire to become
Former SpaceX Head of Talent : I think Elon is smarter than Einstein.
"One way we explained the SpaceX culture, in order to be honest with people, was this:
SpaceX is like special forces. We take on missions that others consider impossible. This will be the hardest thing you ever do in your life.
It attracts the kind of personality that wants to be a Navy SEAL, but in engineering. It will be bruising, punishing, and uncomfortable every day.
Growth is not comfortable. If you are comfortable, you are probably not growing. To work for Elon is to be comfortable living in a constant state of discomfort.
He has 10,000 times more going through his brain than the average person at any given moment. Our ability to think about and analyze a problem is nothing compared to how his brain works.
Elon aspires to be the greatest engineer in the history of the world. He has the cognitive horsepower of the geniuses who came before us.
But he is not Einstein, is he?
I think he is smarter than Einstein."

英伟达炸场!机器人开启「终身自学模式」
刚刚,英伟达放出了一套能让机器人持续成长的技能库——ASPIRE。
ASPIRE有点像一个机器人版Coding Agent。
以前的机器人:参数固定、不会复盘、失败白失败,永远从零试错。
现在的机器人,靠 ASPIRE 拥有了人类式成长思维。
简单说:就跟GPT能把你的prompt、工作记录炼成可复用的skill一样,它也会把机器人的一次次失败和修复,沉淀成之后能继续调用的经验。只不过,它review的不是代码,而是机器人的操作过程。每当机器人执行任务时,ASPIRE就会把感知、导航、抓取、碰撞、运动规划这些过程都记下来。
它背后调用的GPT / Claude则会像研究员一样,判断任务中哪里出了问题,迭代程序。如果跑通,就把沉淀出来的经验写进Skill。 由此,机器人就可以通过写代码、看执行轨迹、修程序、沉淀技能来持续学习。
举个例子:
靠近物体总撞障碍物,传统机器人只会反复翻车。
ASPIRE 会自己总结:换45°/90°多角度绕行,下次遇到任何物体直接复用这套技能。
过去 Code as Policy 最大的坑:不长记性、经验清零。
ASPIRE 彻底根治:做过的坑、修复的逻辑,全部永久入库。
正如英伟达团队所说:
现在机器人做完100次任务,再也不像第一次那样一无所知。
从「死模型权重」到「活的技能经验」,
这才是真正的具身智能进化。
机器人的自学时代,正式开始了。

Elon Musk on the physics of truth:
“Truth is not an easy thing
But you can aspire to the truth. You can try to get as close to the truth as possible with minimum error while acknowledging that there will be some error in what you’re saying
This is how physics works. You don’t say you’re absolutely certain about something, but a lot of things are extremely likely
Aspiring to the truth is very important”

Faith in humanity is a rational hope that, by choosing the path of reason and compassion, it can overcome its own limits and rise to the level of a mature civilization.
: The author defines faith in humanity as a rational hope grounded in reality rather than wishful thinking. It is the conviction that by consciously choosing the path of reason and compassion, humanity can overcome its own limitations and rise to the level of a mature civilization.
This faith acknowledges our flaws selfishness, short-sightedness, tribalism but refuses to accept them as permanent. It trusts in our demonstrated capacity for growth, learning, and moral progress. Reason gives us the tools to understand and solve problems; compassion gives us the motivation to use those tools for the benefit of all.
When these two forces work together, they become a powerful transformative current capable of reshaping societies, institutions, and human relations. Faith in humanity is therefore not passive belief but an active orientation a commitment to build, to improve, and to aspire higher, even when the path is difficult.
It is the quiet but firm assertion that we are not doomed to repeat the mistakes of the past. We can do better, and we should.

Elon Musk’s message to young entrepreneurs:
"Try to be as useful as possible. I think if you aspire to do true work, your probability of success is much higher. Do whatever it takes to succeed. Smash your ego, be humble. It's a super big deal."

Mark Zuckerberg told employees in a Wednesday memo that laying off 8,000 workers was necessary because “success isn’t a given.”
The full memo, as published by businessinsider.
"Hey everyone,
I want to express my gratitude to everyone leaving today for all of the hard work you've put into serving our community.
It's always sad to say goodbye to people who have contributed to our mission and to building this company. I feel the weight of that, and I'm spending a lot of time making sure we manage this as well as possible.
This is the most dynamic I have seen our industry. I'm optimistic about everything we're building to give billions of people the power to express themselves and connect with the people they care about. I'm also optimistic about delivering personal superintelligence to everyone. We've always focused on putting power in people's hands. This is how we believe progress is made in the world. These values are what makes us different, and they are why Meta has been successful.
But success isn't a given. AI is the most consequential technology of our lifetimes. The companies that lead the way will define the next generation.
We're transforming our company to make sure it will always be the best place for talented people to have the greatest impact. People tell us that they appreciate the ability to take greater ownership and execute their vision with less bureaucracy and management to navigate. At the same time, we also want to provide everyone with as much stability as possible. We won't always get this balance right, but I care deeply about this so we'll keep adjusting and work hard to do right by people along the way.
To that end, I want to be clear that we do not expect other company-wide layoffs this year. I also want to acknowledge that we haven't been as clear as we aspire to be in our communication, and that's one area I want to make sure we improve.
I'm confident in what we're all building together. We are one of the few companies positioned to help define the future. Meta has the talent, the infrastructure, the apps and distribution, and the business model. We have a lot of work ahead, but what's on the other side is going to be extraordinary.
Once again, I'm grateful to those leaving today. And I'm grateful to everyone around the company for all of the historic work we will continue doing together.
Mark"
