For a bit of context there are some classically very hard things going on in this video, so if you're not impressed, be glad you didn't have to try to build this 10 years ago.

- Coordinating two hands

- Mobile body

- Deformable objects

- Thin affordances (bag zip in particular)

- Multi-object single grasp

Really a host of things that had individually been tackled as either perception or manipulation problems and probably led to more than one person's PhD here on HN.

"Steel is one of the classic alloy examples: mostly iron with a dash of carbon and other elements, making it much stronger and harder than iron on its own."

Statements like this had me confused for years about how steel is made. Steel is raw iron ore with some carbon removed. (Among other things) Pure iron isn't common in nature, it's usually found instead with too much carbon. That is, to have the properties we like in steel.

Fight extremism with extremism I guess? Maybe we don't have to be either "world govt" or "help me get away with murder". It's ok to say things will be messy and complicated and that limited regulation is probably good even if we agree totalitarian control is bad.

Can we have less terrible voices please? Nothing that sounds like a bubbly millennial. Literally anything that has gravitas.

It's implied, and I'm hoping it's true, that this is a map-less navigation. Which is impressive. This kind of task is much easier if you have a pre-captured map of the environment, but if they are doing this without a map it's great. Historically you were always faced with "The Kidnapped Robot" problem where robots that didn't know where they were couldn't navigate even a little bit. Here the robot appears to be able to follow directions as long as they are interpretable from its current vision (or via dead reckoning).

This is search. Please don't reinvent search with a new acronym.

Agents can use Google. They can also see all the same signals humans do to judge quality. Maybe there's a need for a specialized directory, but does it need a spec or an acronym? No.

Not a physician. Some observations on these statements.

The predicate is "given how we practice medicine and the limits of humans ability to interpret the imaging modalities we have."

The more specific predicate is "for my specialty would this replace or prove superior to the tools that I have?"

Both of these are totally reasonable, however the history of medicine, and science in general, is that creating new ways to look at things has a tendency to reveal information that we never knew we needed.

For example, for years I thought of blood sugar as something that was either in a good or bad range. Then I tried a continuous blood sugar monitor. The full picture of the body's response to specific foods that I ate was eye opening. There's so much more to learn when you get a higher resolution (temporal in that case) view into your body.

Another wonderfully hopeful example is the retinal imaging ML work done by google. A completely non-invasive image of the retina for diabetic issues, that also happened to be able to predict things like age, sex, smoking status, previous cardiac events and more! Just take high-res pictures of things! The body is interconnected in ways that you can infer from one system so much about others.

So while I don't think anything the Dr. said is "wrong", I think it represents a very common blinkered mindset of pragmatic practitioners who need to deliver reliable performance daily.

Shutting down the growth prospects of a company based, not on its behavior, but on the capability of its models right before the IPOs of the companies you're going to profit from is staggeringly dumb. Yes the public is stupid when it comes to investing in stocks, but come on. If these companies growth prospects rest in large part on continuing to improve their products and the government said that if they do they face National Security Cease and Desist letters, then investing is a bad idea.

The selfish / corrupt thing to do is to do this after you've fleeced the public.

Ah, ok. There's a whole body of literature here that I think divides our opinions. I would recommend "Why Civil Resistance Works: The Strategic Logic of Nonviolent Conflict (Columbia Studies in Terrorism and Irregular Warfare)" to start. The history of effective change in the face of organizations acting in bad faith may not be what you think it is.

Sorry if I was unclear. I don't work in finance. I do work with agents. I think expert engineers in finance who are guiding agents are adding a lot of value because of their knowledge of finance. Because I lack that knowledge of finance, even given access to agents, I would not accept a role guiding agents in a finance company because I wouldn't be able to guide the agents well and my/our output would be bad.

"I ended up working in software development roles in the domains of finance, bookkeeping and payment processing, where I had great autonomy and a close and candid relationship with Product Managers and stakeholders.

I learnt a lot about the domain and how to effectively write programs for it: PCI compliance, double-entry ledgers, escrows, reconciliation, payment lifecycles, bank transfer idempotency, etc.

It was, then, obvious that I should focus my career on becoming an expert on that domain to stand out as a professional and differentiate myself in a field that showed signs of an increasing need for domain specialists."

The point being that we're beyond where that's a responsible choice. Empathy for an organization enforcing its rules above the actions of those protesting them means either an ideological alignment with the censorship or an ignorance/disbelief of the severity of the harm the organization is causing. The former audience will never be persuaded. The latter require education and persuasion, and while its useful to create a sense of martyrdom via forcing the enemy to act in an obviously unreasonable fashion, it's a waste of time to argue with their definitions of rules. If the rule were "you are not allowed to say the governing body is corrupt" and they say its corrupt, that exposes clearly and plainly the problem, and enforcement of the rule provides no authority because the rule itself is obviously designed to quash dissent. If the listener is so blithely oblivious to how the intent of a rule has been manipulated to quash dissent, as it has here, then there is no loss in squarely addressing that. "We are protesting your abandonment of scientific principles" is both what they were doing and should be doing.

Wut? I pilot LLMs all day but there's no way in hell I'd agree to be at the helm of a finance product. That first pillar is still there. Maybe the author isn't aware of the impact they have, but I know, with the evidence of reverted PRs, that when I step outside my area of deep knowledge I can no longer call BS on the agents. Our most capable agent, with access to the same kind of distributed systems the author talks about, is regularly wrong, frequently myopic, and just outright dumb constantly. It's the expertise of engineers on the team that push it back on track.

A reminder to anyone who finds themselves in this kind of situation, do not engage with the rhetoric of the enemy. You cannot win an argument where they set the rules. So here, where they question whether or not they were "protesting" distracts from the reality of a censorious organization that will weaponize regulations it controls without good faith. Instead you need a simple, memorable statement of condemnation which is repeated consistently and a clear action which those who hear it can take in response.

"This organization is controlled by Trump loyalists. They are not scientists. You do not owe them respect. Speak over them. Let no manipulation go unchallenged or derided."

Deepmind hype is the worst hype. They do genuinely cool stuff and talk about it publicly, but don't make it available. Or it's only available to a tiny select few. Just shut up about the things you're doing until they are ready. You're part of a consumer products company, not a university PR department.

Huge fan of zoning reform, however I'd love to see equal effort in lending reform. The availability of multi-million dollar mortgages on 30 year terms means that we all get poorer. Getting people into owned homes is a dream left over from the Clinton era that has warped into an ever expanding pool of debt and over sized buildings. Developers will build to the limit of what people can afford (and slightly beyond), and that is defined by mortgage policy. The harsh reality is that as long as you're supporting a system where a 1k sqft house can cost 300, 400, 500k you're not helping anyone who isn't in the business of lending. The only way to reverse the trend is to limit the pool of available capital and bring the sale value of property down.

I don't understand how people can use the phrase "right-size" without a crushing sense of embarrassment and shame. Did you swallow a business consultant from 1990? That and phrases like "go forward strategy" say either 1. I do not know how to communicate like a human or 2. I am afraid of speaking naturally because it impinges on my self image as a business leader or 3. I do not want to accurately describe what I'm doing because that might expose my fragile ego to the possibility that I'm doing something which hurts people.

"We're firing a bunch of people because we think we don't need them anymore due to AI and we'll make more money without them."

There are times when businesses must fire people to stay afloat and it's a business that objectively needs to exist. This isn't one of them, so don't waste everyone's time with your BS, please.
