Three thoughts on what really matters:

1. Fuck cancer
2. Friends are irreplaceable
3. The new "Marcus test" for AI is when AI makes a significant dent on cancer

May that happen sooner, much sooner, rather than later.

In memory of my childhood friend Paul.

@LuizaJarovsky the reporter in question has clarified this statement in multiple ways:

[Shashank Joshi @shashj]

An update. A US official tells me that Sen. Warner misunderstood the NSA director Gen. Rudd in this case. Rudd did use the 'hours, not weeks' wording, but the use of Mythos in this context was—as widely assumed—part of a red-teaming effort, i.e. testing the security of internal networks. The official also told me that the agency's red-teams no longer have access to Mythos, because their authority for accessing it was under Project Glasswing.

oops

Goldman reckons that AI will create about $10trn of discounted value for the world, or up to $22trn. But markets have priced in $27trn of additional value creation. So the size of the "bubble" has now reached $5trn or up to $17trn...

[The Wall Street Journal @WSJ]

The new mantra is that AI can do pretty much everything better than humans. But that isn’t true. https://t.co/1zLI291Y9f

@VoteforPedro he wasn’t first; he is not in the lead; nobody reputable ever said it was impossible; and his tech just apparently killed someone, driving into a house.

[Gary Marcus @GaryMarcus]

Why oh why do so many people take this man’s predictions seriously?

[Gary Marcus @GaryMarcus]

@nminow yep

[Gary Marcus @GaryMarcus]

So, um, if I have this right, the world basically just paid for about 75 billion dollars for a tiny slice of an Elon Musk NFT, with a marginally profitable rocket company thrown in.

How’s that gonna turn out?

It seems almost too dumb to be true, but apparently the literal belief of SaaS bears is "all software is a 0 because Claude can one-shot these apps"

Just staggering levels of short-sightedness in that statement

@kymcoffey *the many predictions

[Gary Marcus @GaryMarcus]

@kymcoffey 1. he has made the two predictions.
2 he’s been consintely wrong about these things for more than a dozen years across a wide range of of circumstances
3. his errors always build up his product to unrealistic levels, which have driven unrealistic valuations

[Gary Marcus @GaryMarcus]

@kymcoffey it’s all sourced. he said all those things.

from the man who brought you SpaceX

[Ramy @TeslaXplored]

1 year since Tesla RoboTaxi launched!
Where are the autonomous RoboTaxis covering 50% of the US population? And where are the 7 new cities 1H2026?
These were not posts or random talking points. These things were said on an earnings call and earnings deck.
What’s going on? $TSLA

[Gary Marcus @GaryMarcus]

By the end of the decade and maybe a lot sooner, we will wonder why we ever treated these folks like they were gods.

[jeffrey lee funk @jeffreyleefunk]

“The more I listen to AI company CEOs, the stranger they sound,” says another tech founder. “They’re full of ideas that no normal person can relate to, talking past the people they’re supposed to reach." They listen too much to investors. https://t.co/Rb9c1Iz5Ag

[Kareem Carr, Ph.D. @kareem_carr]

Software engineering is a weird niche where AI has been insanely effective, but it's not very representative of knowledge work in general.

This leads people in tech to have a hugely distorted view of how impactful current AI is or can be for knowledge work outside of coding.

Our new incident response report exposes a coordinated network of 340 Facebook pages, largely operated from Vietnam, flooding feeds across Canada, the US, the UK, and Europe with AI-fabricated news, and inadvertently funded by Canadian public and private advertisers. 🧵

[Emma Pierson @2plus2make5]

New piece in @TheAtlantic!

We always hear that AI will cure cancer, and I would immediately benefit if it did. But I argue that racing ahead on generalist AI models creates unclear benefits for cancer that are outweighed by broader societal harms.

Only one of these two countries is risking blowing up its entire economy on speculation.

Astonishing difference between US and Chinese AI capex, even after taking into account differences in PPP
