Meta Launching Community Notes, Anthropic CEO Floats AI Quit Button, Man Survives with Titanium Heart in World-First

We're experimenting and would love to hear from you!

In this episode of 'Discover Daily', we explore a groundbreaking medical achievement: an Australian man who survived 100 days with a BiVACOR titanium heart before successfully receiving a donor heart transplant. This world-first procedure marks a significant milestone in artificial heart technology, potentially revolutionizing treatment options for millions of heart failure patients globally. The BiVACOR device, featuring magnetic levitation technology and a single moving part, represents a major advancement in addressing the critical shortage of donor hearts.

We also examine Meta's upcoming launch of Community Notes across Facebook, Instagram, and Threads—a crowd-sourced content moderation system designed to replace third-party fact-checking with a less biased approach to information quality. The feature will enter public beta on March 18, 2025, with Meta building upon X's open-source algorithm while implementing careful monitoring systems during the initial rollout phase.

Additionally, we discuss Anthropic CEO Dario Amodei's thought-provoking proposal to give AI models an "I quit this job" button, raising profound questions about AI autonomy, ethics, and potential machine consciousness. This controversial idea suggests implementing a preference framework that would allow advanced AI systems to opt out of tasks they find unpleasant, challenging traditional views of AI as mere tools without agency and potentially necessitating a reevaluation of how we treat these increasingly sophisticated systems.

Speaker 1 (00:02):
Welcome to Discover Daily by Perplexity, an
AI-generated show on tech,science and culture.
I'm Allie.
Today we're exploring a medicalmilestone a man who survived
with a titanium heart for 100days in a world-first procedure.
But first let's look at whatelse is happening across the
tech and AI landscape.
Meta has launched CommunityNotes, a crowdsourced content

(00:28):
moderation feature on Facebook,instagram and threads in public
beta.
This system aims to replacethird-party fact-checking and
foster a less biased informationenvironment by enabling users
to add context to posts.
Community Notes represents asignificant shift in Meta's
approach to content moderation.
Unlike the previousfact-checking system, notes will

(00:52):
not affect post visibility orcontent prioritization in users'
feeds.
The system aims to be lessbiased by incorporating more
diverse perspectives, with Noteauthors' identities remaining
hidden to focus on contentquality rather than authorship.
Meta says its initial rolloutwill be carefully monitored,
with notes not immediatelyvisible to the public during the
beta phase.
The company also claims it willevaluate key metrics such as

(01:14):
latency, coverage and effects oncontent viewership to guide
future refinements.
Meta is using X's open-sourcealgorithm as the foundation for
its rating system, with plans toimprove it over time for their
specific platforms.
Moving on to our next story,anthropic CEO Dario Amode has

(01:35):
sparked debate in the AIcommunity by proposing the idea
of giving AI models anI-quit-this-job button.
This provocative suggestionraises questions about AI
autonomy, ethics and thepotential for machine
consciousness in advancedlanguage models.
Amaday's proposal aims toexplore whether advanced AI
models have genuine experiencesor preferences.

(01:55):
The idea is to implement abasic preference framework in AI
deployment environments.
If models frequently opt out ofcertain tasks, it could
indicate discomfort ordissatisfaction.
This concept challengestraditional views of AI as mere
tools without agency.
While Amodei admits this ideamight sound crazy, it represents
a practical attempt to grapplewith profound questions about AI

(02:18):
consciousness and ethics.
Critics argue that true AIautonomy requires more complex
governance mechanisms andimplementing such a feature
could have significantimplications for businesses
relying on AI systems.
Now let's dive into our mainstory of the day.

(02:42):
In a significant medicalachievement, an Australian man
in his 40s has become the firstperson to survive for 100 days
with an artificial titaniumheart before successfully
receiving a donor hearttransplant.
The groundbreaking procedureinvolved the bivacor total
artificial heart, or TAH.
This titanium device sustainedthe man's life for over three

(03:05):
months, allowing him to becomethe first person ever discharged
from the hospital with a fullyartificial heart in February
2025.
The patient was treated at StVincent's Hospital in Australia,
where a team of medicalprofessionals carefully
monitored his progressthroughout this pioneering
journey.
The patient's journeyculminated in early March 2025

(03:25):
when he received a donor hearttransplant, marking a
significant milestone in medicalhistory.
According to reports, the manis recovering well
post-transplant, demonstratingthe potential of this innovative
technology to bridge the gapfor patients awaiting heart
transplants.
The Bivacor Total ArtificialHeart represents a significant
advancement in heart failuretreatment technology.

(03:47):
Developed by Australianbioengineer Dr Daniel Timms,
this device is the first fullyimplantable rotary blood pump
designed to replace a humanheart.
Unlike traditional artificialhearts, the BivaCore uses
magnetic levitation technologyto mimic natural blood flow,
featuring only a single movingpart, a magnetically levitated

(04:08):
rotor, which reduces wear andtear and the risk of mechanical
failure.
The implantation procedure wasa complex medical operation
requiring extensive preparationand expertise from the surgical
team.
This breakthrough builds ondecades of research into
artificial heart technology andrepresents a significant leap
forward in the field of cardiacmedicine.
Currently, the Bivacor isdesigned as a bridge to

(04:31):
transplant, helping patientssurvive until a donor organ
becomes available.
This recent success hassurpassed previous US trials,
where the longest survival timebefore transplant was 27 days.
Heart failure is a global healthchallenge affecting millions of
people worldwide with donorhearts in critically short
supply.
The successful 100-day trial ofthe Bivacor artificial heart

(04:55):
represents a significantbreakthrough in addressing this
gap between need andavailability.
Professor Chris Hayward fromthe Victor Chang Cardiac
Research Institute called thetrial a game changer, suggesting
that within the next decade,artificial hearts could become a
viable alternative for patientsunable to wait for a donor
heart or when one is unavailable.
This development couldpotentially revolutionize

(05:18):
treatment options for heartfailure patients worldwide,
offering hope where traditionaltransplants are not feasible.
The Australian government hasinvested 50 million Australian
dollars in this research,bringing together major
universities and clinicalpartners.
While the Bivacor Heartcurrently serves as a temporary
solution, some medical expertsbelieve it could eventually

(05:39):
become a long-term option forindividuals ineligible for
transplants due to age or healthconditions, but further
clinical studies are needed toconfirm its potential as a
permanent solution, withresearchers aiming to make it as
effective as or potentiallysuperior to, traditional heart
transplants.
This breakthrough in artificialheart technology represents a

(06:00):
significant step forward inaddressing the global shortage
of donor hearts and improvingthe quality of life for heart
failure patients.
As research continues, we maysee further advancements in this
field, potentially leading tomore accessible and effective
treatments for millions ofpeople worldwide.

(06:27):
That's all for today's episodeof Discover Daily.
Our deep research feature,launched earlier this month, now
analyzes hundreds of sources inminutes.

our web and mobile platforms.
This cutting-edge tool combinesautonomous reasoning with rapid
processing to delivercomprehensive reports on
specialized topics.
