The longevity industry aims to let everyone enjoy a healthy, active life well past the age of 100. But the question everyone will be asking is... will it happen in my lifetime?
Manuela Saragosa reports from the Longevity Forum conference in London, where hundreds of researchers, investors, entrepreneurs and policymakers have gathered to try and answer this question.
Among them, she speaks to billionaire investor Jim Mellon; London Business School economist Andrew Scott; the youthful venture capitalist Laura Deming; Columbia University geriatrician Linda Fried; and cryonics fan Anders Sandberg of the Future of Humanity Institute.

Quantum computers: What are they good for?
Google claims to have achieved a major breakthrough with "quantum supremacy". But what could quantum computers actually do, and how soon will they be useful?
Manuela Saragosa speaks to Harvard quantum computing researcher Prineha Narang, who says that the devices she is working on are annoyingly "noisy", but could still make an important contribution to tackling climate change in the next few years.
There are fears that quantum computers could one day crack modern encryption techniques - rendering private communications and financial transactions unsafe. But IBM cryptography researcher Vadim Lyubashevsky says don't worry, they've got the problem in hand.
Plus, the BBC's technology correspondent Rory Cellan-Jones delineates the greatest paradox of quantum computers - that nobody can explain how they work.

The ethics of AI
One of the world's top thinkers on artificial intelligence, tells us why we should be cautious but not terrified at the prospect of computers that can outsmart us.
Professor Stuart Russell of the University of California, Berkeley, tells Ed Butler where he thinks we are going wrong in setting objectives for existing artificial intelligence systems, and the risk of unintended consequences.
Plus IBM fellow and computer engineer John Cohn talks about blockchain, deep neural networks and symbolic reasoning.

The billionaires who want to pay more tax
Liesel Pritzker Simmons and her husband Ian Simmons are billionaires who come from successful US business families. Liesel's family is best known for founding Hyatt hotels. Both say the the US government should be collecting more tax from super-rich people like them. We asked them why. And Dr Ted Klontz, associate professor of practice and financial psychology at Creighton University in the US, explains the psychology of a billionaire.

Who wants to be a billionaire?
Should the richest be taxed out of existence? Manuela Saragosa hears from Emmanuel Saez, a US-based French economist advising US presidential hopeful Elizabeth Warren on a wealth tax targeting the super rich. The arguments against taxing billinaires more come from Chris Edwards, an economist at the libertarian Cato Institute in Washington DC.
