AI is already discovering new cures
As part of a wide-ranging conversation on the GZERO World podcast, oncologist and Pulitzer prize-winning author Siddhartha Mukherjee walks Ian Bremmer through one of the most groundbreaking uses of AI in medicine today: generative drug discovery. It’s not just about speeding up research—it’s about creating entirely new molecules that no human has ever seen.
Using AI, researchers can now analyze the shape of a dysfunctional protein—like one found in a cancer or autoimmune cell—and generate chemical compounds that could bind to and modify its behavior. “This is true generative chemistry,” Mukherjee says. “Every time we do this in collaboration with a machine, the machine learns it, and it learns it forever.”
The process is like solving a puzzle with a million possible pieces. With each failure, the AI learns more, narrowing down candidates until it finds a match. It’s already produced new antibiotics with never-before-seen structures—and Mukherjee believes this is just the beginning of a medical revolution.

How AI is transforming medicine, and the cancer fight
In 1971, President Nixon declared a “War on Cancer.” Fifty years and billions in research later, the disease still kills 1,700 Americans a day—and survival often depends on income, race, and access to care. But could artificial intelligence finally give humanity the upper hand?
On the latest episode of GZERO World, Ian Bremmer sits down with cancer researcher and bestselling author Siddhartha Mukherjee to explore how AI is changing the trajectory of modern medicine. From early detection and diagnostics to drug discovery and personalized treatment, Mukherjee believes we're entering a new era in the fight against cancer.
“The machine learns it, and it learns it forever,” Mukherjee says, describing how AI can now generate new chemical compounds that have never existed—potentially designing cancer drugs from scratch. “You don’t need to train a new generation of chemists. The machine will now learn it for eternity.”
Mukherjee explains how this generative power can unlock faster, cheaper breakthroughs across all stages of cancer treatment—from identifying new carcinogens like “forever chemicals” to tailoring therapies to a patient’s specific biology. For a disease that touches almost every family, these advances aren’t just technological—they’re deeply personal.

How AI will revolutionize medicine with Siddhartha Mukherjee
Listen: Nearly 1 in 2 men and 1 in 3 women in the US will be diagnosed with cancer, and 1,700 people die from it every day. Disparities persist—Black women are 40% more likely to die of breast cancer than white women—and treatment costs remain crushing for many.
On the latest episode of the GZERO World podcast, Ian Bremmer talks with world-renowned cancer researcher and Pulitzer Prize-winning author Siddhartha Mukherjee about the future of medicine—and why artificial intelligence might finally tip the scales in the decades-long war on cancer.
Cancer remains the second leading cause of death in the US, killing nearly 1,700 people every day. But Mukherjee says AI is already reshaping the field, from radiology and diagnostics to identifying new carcinogens and designing entirely new cancer drugs. “Every time we do this in collaboration with a machine,” he explains, “the machine learns it, and it learns it forever.”
In a wide-ranging conversation, Mukherjee breaks down three major areas where AI is advancing medicine: patient care, data mining, and generative drug development. He also weighs in on early cancer detection, how inflammation may hold the key to understanding new carcinogens, and why this moment may be the most hopeful in half a century of cancer research.

50 years of the war on cancer
We've been fighting a war on cancer for over half a century—from Nixon’s 1971 National Cancer Act to the promise of cutting-edge AI therapies today. Ian Bremmer reflects on how that war is going.
The numbers are still grim: nearly 1 in 2 men and 1 in 3 women in the US will be diagnosed with cancer, and 1,700 people die from it every day. Disparities persist—Black women are 40% more likely to die of breast cancer than white women—and treatment costs remain crushing for many.
But there’s progress. Survival rates have more than doubled since the 1960s, and new technologies, especially AI, are opening doors researchers couldn’t imagine a decade ago. For Ian, it’s personal. Both of his parents died of cancer. “If you haven’t had it yourself,” he says, “you know someone who has.” But for the first time in decades, there’s real hope that science may be gaining the upper hand.

Here’s what you missed while you were away
As summer winds down this weekend, here are the geopolitical stories you may have missed while your inbox was on “out of office” — the ones we expect will have the biggest impact this fall.
In Sudan, the skies have turned deadly
Drones have become the new face of modern warfare, dominating headlines as Russia and Ukraine trade near-daily aerial strikes. But unmanned aircraft vehicles (UAVs) are wreaking havoc in another of the world’s deadliest, and least covered, conflicts: Sudan.
With drones now entering the fray, the conflict risks escalating into a dangerous new phase, allowing both sides to keep inflicting damage with minimal risks to themselves.
Ever since the SAF recaptured the capital Khartoum in March, the two sides have been locked in a strategic stalemate, with drones enabling both groups to carry out precision strikes hundreds of miles behind enemy lines.
Is Sudan a sign of future of warfare? Read more here.
A surge of political violence has revived Colombia’s worst fears
When a gunman shot Colombian presidential candidate Miguel Uribe in June, it sparked memories of the deadly decades-long internal conflict from late last century when political assassination attempts were a common occurrence.
Fast forward nearly three months, Uribe is now dead, and the violence between dissidents and the military has intensified – there have been multiple reports of mass kidnappings of government soldiers. Left-wing President Gustavo Petro has pledged to clamp down on the violence, but he can’t seem to put a lid on things: the number of kidnappings and killings of human rights activists have soared over the last few years.
This will likely cost the left, politically speaking. The rising violence is prompting more and more Colombians to seek a tough-on-crime leader, damaging Petro’s hopes that a socialist candidate will win next year’s presidential election – the incumbent leader can’t run again.
The shift in Colombia’s politics is also something of a proxy for the rest of South America. Other countries with left-wing leaders, like Bolivia and Chile, have also tilted right, seeking leaders who will keep them safe. Bolivians ousted the socialists from power for the first time in decades. Chile’s elections in November will be the next test for the South American left, before Colombia’s election next May.
Will the rising violence hurt the Colombian left? Read more here.
Is MAGA bailing on Bibi?
In early July, there were some rumblings of discontent within the Trump administration at Israeli Prime Minister Benjamin Netanyahu. An Israeli shell had struck a church in Gaza, settlers had attacked a Christian Palestinian village, and the Israeli Defense Forces had bombed the Syrian Defense Ministry in Damascus – against the White House’s wishes.
But the disquiet was only the tip of the iceberg: Trump supporters, especially younger ones, are becoming more and more critical of Israel, questioning the US’s support for the Jewish State. Though younger Republicans aren’t nearly as critical as younger Democrats, this trend is a concerning one for Israel, as the country has relied heavily on US military aid. Republicans have been particularly sympathetic toward Israel in recent history, so to lose their backing would be drastic.
Soon after the piece was published, US Rep. Marjorie Taylor Greene – a MAGA firebrand – became the first House Republican to label Israel’s actions in Gaza as a “genocide,” affirming that the GOP is no longer united behind supporting Israel. Read the original GZERO report here.
Is AI why college grads can’t find jobs?
The kids are not alright. Since we opened the Pandora’s Box of chatbots, new grads have faced higher unemployment than the national average for the first time in decades. Which raises the question: are they the canaries in the coal mine that AI-driven job disruption has begun?
“It just seems like there’s not any more entry-level roles,” reports James Kettle, a 25-year-old Columbia University graduate who’s been on the job hunt since May. His experience is echoed in a new Stanford study, which found hiring in AI-exposed occupations for early-career workers is down 13%.
Even if we can’t be certain AI is totally to blame for stealing young people’s existing jobs (yet), it’s making it harder for them to get hired in the first place. Delia Thompson, a 23-year-old University of Virginia graduate who’s been on the hunt for seven months, describes the job process today as “shouting into the void,” as she and other candidates send thousands of AI-assisted resumes through LinkedIn, only for companies to use their own algorithms to sift through the pile – a loop of bots talking to bots. “It makes it feel like a total lottery,” says Thompson.
This is reshaping their political views and how many young people are viewing AI overall. Read more here.
The Royal Embassy of Cambodia in Bangkok, Thailand on July 24, 2025. The two countries’ long-simmering border dispute turned violent on Thursday.
What We’re Watching: Clashes on Thailand-Cambodia border, Trump’s new AI plan, China-EU tensions
Thailand and Cambodia on the brink
A long-simmering border dispute between Thailand and Cambodia erupted into armed clashes Thursday that have killed at least 12 people on the Thai side of the frontier. Thailand has launched cross-border airstrikes in response to what it said was Cambodian artillery fire. The dispute dates back more than a century, but things have worsened since May, when a Cambodian soldier was killed in a border skirmish. The issue has also roiled Thai politics: Prime Minister Paetongtarn Shinawatra was ousted earlier this month after a leaked phone call revealed her buttering up influential Cambodian politician Hun Sen and disparaging her own country’s military.
Trump unveils AI plan
To stay ahead of China in the race to dominate artificial intelligence, President Donald Trump unveiled a sweeping plan Thursday to boost the US industry by slashing regulatory red tape and ramping up exports of US-made tech to allies – reversing Biden-era guidelines. Under the plan, US states would also be prohibited from developing their own AI rules, and the federal government would cut funding to “biased” models. Critics warn the strategy sacrifices important safeguards regarding jobs, the environment, and disinformation, but Trump and his team say speedy innovation is the only way to stay ahead of China.
China-EU summit reveals ongoing frictions
The China-European Union summit in Beijing on Thursday was meant to celebrate 50 years of bilateral ties, but the tensions were clear. European Commission President Ursula von der Leyen demanded “real solutions” to deepening “imbalances”, echoing wider EU complaints that China floods European markets with products, particularly electric vehicles, that are unfairly cheap because of Chinese state subsidies. President Xi Jinping’s response? “The current challenges facing Europe do not come from China,” a pointed suggestion that the two sides share an interest in closer ties at a time of tariff pressure from the Trump administration.
AI for the entrepreneur
At the 2025 AI for Good Summit in Geneva, GZERO’s Tony Maciulis sat down with AI educator and content creator Natalie Choprasert, whose mission is to make artificial intelligence more accessible to everyday business owners.
With a massive following on TikTok and other platforms, Choprasert helps demystify AI tools and implementation, without the jargon. “Business owners don’t have time to test every tool,” she says. “Start with what fits your workflow, not what’s trending.”
In a world overwhelmed by rapid AI releases and rising misinformation, she also warns of new risks, from CEO scams to deepfake fraud, but believes clear labeling and education can build trust. Still, Choprasert remains optimistic: “AI has opened doors I never thought possible as a solopreneur.” Her message: AI isn’t just for tech giants, it’s a force multiplier for creatives, small businesses, and creators everywhere.

Skilling for the AI era: What do you need to succeed?
"AI isn’t one thing, it’s everything, everywhere, all at once,” says Naria Santa Lucia, General Manager of Microsoft Elevate.
In this Global Stage conversation with GZERO’s Tony Maciulis at the 2025 AI for Good Summit in Geneva, Santa Lucia explores how generative AI is transforming not just the way we work—but how we prepare to work at all. From lesson planning to law, Santa Lucia argues the most in-demand AI skills aren’t technical. “Curiosity, collaboration, and communication are the real power skills.”
She also highlights what’s at stake: the disruption of entry-level jobs, the future of informal and gig workers, and the urgency of reskilling at scale. “We don’t know all the answers, but we can’t afford to wait for them.”
