Incredibly good advice for the builders out there.
I love this idea from @dhh:
All the best ideas that actually turn out to have an impact sound stupid at first.
“You've got to have a high tolerance for people telling you:
-What you're building is stupid.
-What you're building is ugly.
-What you're building is never going to work.
When I get that feedback, I know I'm onto something.
I’ve found that’s often true about products. You enter some domain and you think:
"Who's the best? Can I just copy them?I'll do a slight tweak."
That's not gonna work.
All the best ideas that actually turn out to have an impact sound stupid at first.
They're not intuitive.
That's where all the value has been locked up. It's locked up in this misconception about what people actually want, because most people don't know what they want.”
If you had the FBI posting about PHP in your predictions for 2026 I want to copy trade you on Polymarket.
The FBI continues to warn about two critical security flaws in PHP, a programming language used to build many websites and online services. Attackers could exploit these vulnerabilities to break into systems, putting sensitive information and business operations at risk. Security updates are available and should be applied immediately.
If you are a business owner or website operator, check whether your systems are affected. Contact your IT support team, website developer, or hosting provider for help identifying vulnerable systems and applying the necessary updates.
The FBI urges organizations to take the following steps now:
➡️ If an immediate update is not feasible it is recommended that organizations take the system offline until it can be fully mitigated.
➡️ Immediately update affected PHP installations following the guidance on php.net. Inventory where PHP runs in your environment, prioritizing internet-facing systems and vendor products that bundle PHP.
➡️ Monitor web servers for suspicious activity, including PHP processes unexpectedly launching command shells or downloading files. Ensure appropriate process-monitoring capabilities are in place to help identify potential exploitation.
➡️ If you find signs of compromise, isolate affected systems, preserve your web server and PHP logs, and report it to your local FBI field office or ic3.gov. Those reports help us identify the actors involved and warn other organizations before they become victims.
For the latest information on these vulnerabilities (CVE-2026-109618 and CVE-2026-109619), follow PHP’s announcements on php.net, CERT-EU Security Advisory 2026-018, and CISA’s Known Exploited Vulnerabilities catalog.
Going all in on sports cards and private islands.
This will never stop. Not being prepared for this is the biggest mistake one can make, whether in business or on a personal level.
An awesome day of endless AI discussions at @Techweek_ LA. The future is bright.
We live in very interesting times. It’s fairly obvious what happens next. The world is nowhere near prepared for how fast AI is progressing.
Today I call upon the blockchain industry to calmly begin planning for "bunker mode". My personal recommendation is to set in motion a controlled mass migration of assets to fresh addresses, i.e. addresses whose pubkeys remain hidden behind a hash.
Holders, starting with large and sophisticated ones, should consider moving the bulk of their funds to addresses that have never signed a transaction. And when they do sign one, they should also move remaining funds to a new address (possibly generated from the same seed phrase).
Don't rush. While I believe there is cause for action a rushed migration would do more harm than good. Don't panic either. Moving assets to protected addresses is a simple, preventative step which does not require new cryptography or new wallets.
IMO it is now reasonable to brace for the possibility that ECDSA breaks before qday, in the worst case in months not years. By "break" I mean fast private key recovery (e.g. in one week) on available hardware (e.g. a large GPU cluster).
Recent days have been humbling for human mathematical intuition. Long-held, unquestioned hypotheses have fallen. This includes the n log(n) bound for integer multiplication and the 3SUM conjecture. In hindsight, May's unexpected disproof of the Erdős unit distance conjecture was our warning shot.
Yesterday's OpenAI drop made it clear that mathematical superintelligence is upon us. They say there are weeks where decades happen. We are about to live through weeks where centuries of mathematical progress happen. Could our magic 64-byte ECDSA signatures be too good to be true? Was it just security through obscurity all this time?
Elliptic curves feel especially vulnerable to superintelligence. Curves carry rich structure, with room for fancy tricks like Schoof, Frobenius, pairings. (By contrast, hashes are designed to minimise algebraic structure.)
Separately, as Ewin Tang can attest, an efficient quantum algorithm sometimes foreshadows an efficient classical one. We should be open to the possibility of a classical counterpart to Shor that breaks elliptic curves and RSA at once.
Also noteworthy is the striking under-representation of cryptographic breakthroughs among the 722 mathematical results OpenAI published. I've witnessed first-hand the US government censoring academic quantum cryptanalysis results. Backroom interventionism is my base case.
I urge large, sophisticated actors to lead by example. Project11's "risq list" (bitcoin-risq-list.projecteleven[.]com) is a great tracker of exposed BTC pubkeys. Binance, Bitbank, Robinhood, Bitfinex, and Tether have an opportunity to harden their cold storage. Next month I'll address institutions in London in a live Q&A (forum.ethereuminstitutional[.]org/london-2026).
Again, please do not rush. Wallets holding under 50 BTC enjoy partial cover from "Satoshi's shield", i.e. his 20K exposed addresses that hold 50 BTC each. Load-bearing signers like oracles and L2 security councils should consider rotating ECDSA pubkeys with every signed message and/or multi-signing with a hash-based schemes like SPHINCS.
Exiting bunker mode safely will require post-AI cryptography. My inclination is to go all-in on hash-based cryptography and avoid structured mathematical assumptions entirely, whether from curves, lattices, or isogenies. A single battle-tested hash (e.g. from the SHA or BLAKE families) yields plausible post-AI security.
The Ethereum roadmap on strawmap[.]org fully embraces hash-based cryptography with end-to-end formal verification as a response to the quantum threat. Those timelines must now be revisited and accelerated in light of mathematical superintelligence. I'll be pushing for maximum defensive acceleration.

Introducing Griffin, the first model to pass the video Turing test.
48% of people who talked to it live thought it was a real human. Previous systems have had a pass rate <3%. It is #1 on NVIDIA's benchmark for full-duplex AI video.
It’s the first Human Interaction Model (HIM).
Readers added context they thought people might want to know
The 48% figure and "video Turing test" claim are from Tavus's own study of 54 one-minute calls, not independently verified or using a standard protocol. Griffin-Lite leads NVIDIA's VideoFDB benchmark on their public leaderboard.

I remember one year ago saying “just imagine how all of these AI videos are going to be a year from now.”

The Fed raised rates by 25 basis points on Wednesday, its first hike since 2023, per CNN. Talk around the SPDR S&P 500 ETF got much louder and only a little less upbeat.
Engagements, 3 hours after the decision: 4.2x the prior day's hourly pace
Engagements today: 6.5M, 1.7x the 30-day average
Mentions today: 7,505
Sentiment: 70%, from 73% before the decision
The amount of talk moved far more than its tone.
