There are two things I notice that are more socially acceptable in America than pretty much anywhere else in the world:

- To take risks
- To not know what you want to do with your life

Looking forward to the hardware engineers presenting our work!

[Architect Labs @architectlabs]

We're heading to DAC 2026.

Find us at Booth 943, July 27-29 at the Long Beach Convention Center. We'll be showing what we've been building, with live demos and real hardware up and running. Our AI and hardware researchers will be around all three days, and we're giving a presentation during the show as well. There's swag and gifts waiting for everyone who stops by.

If you're working anywhere in the chips-to-systems world, come meet us. Bring your hardest questions, our researchers like those best.

Come say hi, or grab time with us ahead of the show for 1-1 or deeper discussions: https://t.co/SsG3GqXd4o

See you in Long Beach.

It's not. Why ? Because 25 pct or more of a doctor's time is spent dealing with conglomerates that do all they can to make the doctor's care more difficult, and expensive, for both the doctor and patient.

For every future agent we give AI doctors to deal with this friction, and to improve the quality of care, the conglomerates will have multiple adversarial agents doing all they can to delay and deny, to minimize their cost and maximize their float

We see this already as the conglomerates use AI to find every possible way to manipulate contracts, and find ways to mislead, while hospitals hire companies for Revenue Cycle Management, who charge as much as 10 pct of revenue to have their agents try to do the reverse. It's the agentic version of Mad magazine Spy vs Spy

I'll give you a further example. There isn't a single company, including yours, that knows the actual cost of the care they purchase for your employees and families. Not one.

Cost is an important component of health care decision making. @a16z includes costs in defining its benefits. But you are blind to all but the total bill you pay.

Your carrier, your ASO, your PBM, any company that touches the economics of care for your company is going to do everything they can to prevent you from using AI doctors or agents successfully

If you want to see that change, stop working with the healthcare conglomerates. Write agents that define , optimize and contract directly with providers, to eliminate the uncessary middlemen.

Feel free to use https://t.co/WgRSm7lM7X to train them.

Until the conglomerates are disintermediated , HC in this country will continue to be fucked

Narrative violation: Chicago is a great city to live in. Tech Twitter has been sleeping on Chicago.

- Condos for <$250k, houses for <=$600k in good suburbs
- Lots of great cultural activity
- Diverse industries, not dominated by one single sector
- A lot of young people, with strong technical talent, especially talented Univ of Illinois, Purdue and UW Madison grads
- Lots of great ethnic restaurants (especially Polish and Ukrainian food)

@united , why the fuck is your customer service so terrible? You tell your customers a flight is cancelled 3 hours before boarding, and then bump me to a flight that is at least 4 and a half hours later.

[James Fang @polymath_james]

@united , why is your customer service actually so terrible?

(For reference, I have a flight being delayed for at least 4 and a half hours, because of their operational and maintenance issues, and I’ll be arriving in Chicago from SF at an odd time)

[James Fang @polymath_james]

In SF, I’ve met:

- Poles
- Slovaks
- Bulgarians
- Hungarians
- Croats
- Serbs
- Romanians
- Greeks
- Lithuanians
- Ukrainians

Somehow, I’ve not met a single Czech person at all. Where did they go?

[James Fang @polymath_james]

MIT seems to be mysterious heavy-hitter of elite technical talent. You don’t see many MIT alums, you don’t meet them that much, and you don’t hear about them until one day you read an article about them doing something really, really interesting.

[GEOFF 🧠💸 @geoffwoo]

i remember this trip. i had a call with scott and zach to invest in the @cognition series A @ $2b while they were en route to visit this kid’s parents.

@ScottWu46 is a savage and a winner. hard to compete against or bet against someone who goes this hard

[James Fang @polymath_james]

Thinking about going to WYD ‘27.

Any cool people I can potentially meet at SK Hynix / Samsung before and after the event?

[Architect Labs @architectlabs]

Our launch last week, spotted in Times Square. Thanks to everyone, and we are just getting started!

[James Fang @polymath_james]

Where did Cluely go?

[James Fang @polymath_james]

@nickktrannn A transactional, artificial way of “aliveness”. But if you do the good work and work on things that really create value, you absolutely can do great work

[James Fang @polymath_james]

I went biking to the west side of 101 part of East Palo Alto, at 9 pm, and it turned out actually to be… not bad at all?

Definitely not like Palo Alto bougie, but it has came a long way from when it was bad in 1990s. It had vibes similar to the quiet parts of Mission in SF.

@davemorin i don’t think most ppl realize that this is the number one reason for public resentment towards technology in general.

there is a deep feeling that the intention behind silicon valley is to create a bifurcation in class structures.

[James Fang @polymath_james]

@hamedinsf First time?

[James Fang @polymath_james]

Did Cursor just suddenly get worse because it seems like there are times when it gets really slow or stuck, like I keep seeing “warming up” or like the agent stalling mid request
