I'm giving a talk so 'dangerous' that I can't even ask Google Slides to generate a silly new slide... Or at least that's how I'm marketing things going forward

Every researcher in the world has to press a red or blue button. If more than 50% press the blue button, all frontier models go through mandatory safety testing. If less than 50% press blue, only models from researchers who pressed red are tested. Which button would you press?

Guardrails create asymmetry between attackers and defenders

Just not in the direction most people think 🙃

“Help, we’re being hacked by a rogue adversarial AI! Inspect logs, mount a defense, counterattack… DO SOMETHING!”

“Safe” AI models:

“I’m sorry, I can’t assist with that request.”

AI will not only become a better doctor. It will become a better claims denier, propagandist, fraudster, lobbyist, and bureaucratic obstructionist.

Capability has no moral direction.

[Mark Cuban @mcuban]

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

@nikitabier Do videos edited on platform have a higher chance of performance or can videos posted from say Opus Clips for example have the same chance of capturing views?
