Replying to @a16z
@a16z State of Longevity report is out!
@evajsteinman and I surveyed 500 Americans to predict what's next.
We're also interviewing people at the cutting edge of health & tech about what they do themselves. My interview with @hubermanlab is out today.

I may be able to help shed some light here.
While they all sound similar, I hear a lot of people use "passphrase", "passkey", and "password" interchangeably.
What makes it even more confusing is that you can store all three of those things in your password manager 🧵
This is correct
Passkeys should be used as passwords, since they're stored in a password manager
They're "supposed" to use biometrics, but realistically they don't, you just unlock your password manager and your passkey is stored there
So passkeys are not 2FA, they're single factor authentication
Prove me wrong

We asked GPT-6 Astra to edit Qwen3.5-0.8B weights to improve math.
It directly changed only 0.016% of weights, fixing 0.8B's reasoning loops & improving math up to 6x and even instruction following 3x, without gradients or training.
We call this Weight-Space Programming: frontier LLMs can now natively read/write neural network weights! 🧵

Even founders don't understand it clearly, but they feel it everyday. Thanks for putting a name to it @scottastevenson
Almost no one understands the radical time scarcity of early stage founders.
Here is the math on how spending a couple days on the wrong thing can trigger weeks of treading water to stay afloat:

We believe voice is the most natural way to interact with intelligence, so we created Dessa, the most authentic full-duplex speech model ever built. Talking with it feels like talking with a person…full of emotion, nuance, pauses, and a natural cadence.

Incredibly bizarre thing happening to me: I've gotten really lazy in my prompting because the models are so robust to typos, word misuse, omitting words, etc.
But now I keep catching myself typing out messages the same way in Slack?

I think many of us working in tech tend to forget that the reason software engineering vs other engineering fields pays (a lot!) more, is a lot more flexible (WFH/remote), and has better perks:
Because this field changes much faster than other engineering fields. The premium is because fewer people are able/willing to pick up new technologies, methodologies so quickly.
But the field had ~10-20 years of stability, and so lots of folks forgot this is why a premium exists. And that AI is just another tech wave: software engineers who pick it up and master it will generally fare better; those not will struggle a lot more.

So basically, today PHP got two critical bugs that let anyone run code on your server without even logging in, which is bad, and then the details leaked before the patch was even out, which is worse, and it works on WordPress and MediaWiki and Magento and Joomla and Laravel, and Censys says like 1.5 million servers are running a version with no fix, so the NSA was like "take your system offline," and the FBI was like "take your system offline," and CISA and the UK and CERT-EU were all like "take your system offline," and then the Prime Minister of Japan, the actual Prime Minister, posted at 5:55 in the morning telling 48.8 million people to take their system offline, so everyone took their system offline, like the Dutch cybersecurity agency took its own website offline, and the Dutch parliament went offline, and the Port of Rotterdam went offline, and Finland and France and Denmark started pulling government sites, and Wikipedia went down, and Archive.org went down, and Asana and GOG and Something Awful went down, and the University of Vienna's webmail went down for some reason, and that's just PHP. Because GitLab also dropped a CVSS 10.0, which is the highest score they give out, for a bug that's been there since 2014, so that's every self-hosted GitLab for twelve years, and then LiteLLM 1.107.0 got hijacked and shipped a credential stealer and a remote access trojan in every single wheel and the Docker images, including latest, and you didn't even have to import it, just installing it was enough, and it's the second time this year, and then Railway paused every deployment on the entire platform because someone got into the environment variables, so now everyone has to rotate every secret they've ever stored there, and TiDB Cloud said someone was walking around inside with stolen credentials for basically a month and an extortion group says they took 10.6 terabytes, and Zeabur got breached for the second time in two months and is just shutting down, like the whole company, and Node.js patched remote code execution and a TLS bypass, and CISA says Plex is being actively exploited, and someone took over 300 Tor exit relays to steal SSH passwords, and SafePay ransomware has hit over 600 critical infrastructure orgs, and India's biggest bank filed a data loss incident, and Japan has been in an official state of emergency in cyberspace since October 9, which honestly explains the 5:55 AM post. Oh, and eMudhra, a certificate authority that's issued over 60 million certificates, whose entire job is proving websites are who they say they are, was supposed to be using private keys that are random numbers over a hundred digits long, and one of them was 4. Just 4. And the others were like 66 and 237. Anyway, it's Wednesday.
every day now someone will post like, “⚠️it’s time to lock down your pcrtx mandated caches, they got hit with the pcrtx 3.4.5 vulnerability which allows unencrypted glbdrt files to overwrite the /lxz/vyy subdirectory” and everyone will be like “ah shit of course not vyy”
It's so over

A real thing I'm doing now is telling the models to find interesting ideas from published literature that we can productionize to improve our software, it's awesome lol
