Training is the process of regressing to the mean with respect to the given data. It's no surprise that it wears away sharp corners and inappropriately fills recesses of collective knowledge in the act of its reproduction.

Suddenly all this focus on world models by Deep mind starts to make sense. I've never really thought of Waymo as a robot in the same way as e.g. a Boston Dynamics humanoid, but of course it is a robot of sorts.
Google/Alphabet are so vertically integrated for AI when you think about it. Compare what they're doing - their own power generation , their own silicon, their own data centers, search Gmail YouTube Gemini workspace wallet, billions and billions of Android and Chromebook users, their ads everywhere, their browser everywhere, waymo, probably buy back Boston dynamics soon enough (they're recently partnered together), fusion research, drugs discovery.... and then look at ChatGPT's chatbot or grok's porn. Pales in comparison.
What an upsetting comment. I'm glad you came around but what did you think was going to be effective before you came around to world models?
I've noticed a lot of LLM-based tools that are essentially this sort of thing. Just a slightly more specific prompt wrapper around the core capability that can already do the thing. It's so bad.
That has been the case this entire time. The "ChatGPT-wrapper" startups were little more than a webapp frontend for ChatGPT with a clever prompt.
> It doesn't seem to be all that useful for real, productive work.
Even the most pointless bullshit job accomplishes a societal function by transferring wages from a likely wealthy large corporation to a individual worker who has bills to pay.
Eliminating bullshit jobs might be good from an economic efficiency perspective, but people still gotta eat.
The logic of American economic policy relies on a large velocity of money driven by consumer habits. It is tautological, and it is obsolete in the face of the elite trying to minimize wage expenses.

I would not assume cooling has been worked out.
Space is a vacuum. i.e. The lack-of-a-thing that makes a thermos great at keeping your drink hot. A satellite is, if nothing else, a fantastic thermos. A data center in space would necessarily rely completely on cooling by radiation, unlike a terrestrial data center that can make use of convection and conduction. You can't just pipe heat out into the atmosphere or build a heat exchanger. You can't exchange heat with vacuum. You can only radiate heat into it.
Heat is going to limit the compute that can be done in a satellite data centre and radiative cooling solutions are going to massively increase weight. It makes far more sense to build data centers in the arctic.
Musk is up to something here. This could be another hyperloop (i.e. A distracting promise meant to sabotage competition). It could be a legal dodge. It could be a power grab. What it will not be is a useful source of computing power. Anyone who takes this venture seriously is probably going to be burned.
The materialist take is that his plan is to eventually over-value and then trade on his company valuations, and also have another merger lined up for future personal financial bailouts.

Signal protocol prevents replay attacks as every message is encrypted with new key. Either it's next hash ratchet key, or next future secret key with new entropy mixed via next DH shared key.
Private keys, probably not. WhatsApp is E2EE meaning your device generates the private key with OS's CSPRNG. (Like I also said above), exfiltration of signing keys might allow MITM but that's still possible to detect e.g. if you RE the client and spot the code that does it.
Whatsapp didn't implement Signal's protocol verbatim. They appropriated the core cryptographic security and then re-implemented the rest on their own servers. This removes all guarantees of secrecy as long as they can run arbitrary code on the servers they own.

WhatsApp's end-to-end encryption has been independently investigated: https://kclpure.kcl.ac.uk/ws/files/324396471/whatsapp.pdf
Full version here: https://eprint.iacr.org/2025/794.pdf
We didn't review the entire source code, only the cryptographic core. That said, the main issue we found was that the WhatsApp servers ultimately decide who is and isn't in a particular chat. Dan Goodin wrote about it here: https://arstechnica.com/security/2025/05/whatsapp-provides-n...
Can they control private keys and do replay attacks?

We found an ancient tablet, dated it, reconstruded a long-dead language well enough to read it, reconstructed the night sky on that day, five and a half thousand years ago, found the orbit of this thing, and connected it to a geological formation thousands of kilometers away. Humans can do some amazing stuff.
Humanity is awesome because we are naturally constrained in semantic-space, making it relatively straightforward to reverse engineer things that ancient humans made even if we share basically zero overlap in culture.

Once upon a time, the Unix philosophy was lauded in these venerated halls. "Do one thing and do it well."
Now the hype has seemed to shift to "do absolutely anything just barely well enough to get people to pay for it".

If I understood the chart correctly, even the successful one only found 1/6 of the creatures across multiple runs.
No science detected.
Without comparison to some null hypothesis (a random policy), this article is hogwash.
