In the run up to HowThelightGetsIn festival – the world’s largest philosophy and music festival - in London’s Hampstead Heath September 23 – 24, we asked some of our regular hosts and speakers what they thought the most important debates were for this century. Anders Sandberg, Joanna Kavena, Hilary Lawson, Philip Collins, Bjørn Ekeberg, Barry Smith, Peter Tachel and Myriam François respond.

The most important debate to have in the 21st century is how to coordinate about rapid solutions to emergent global problems. We saw it partially happen during Covid-19, but other crises are plausible - systemic risks, runaway AI and biotech, new forms of crime, etc. We need mechanisms that can quickly mobilize the right parts of humanity, whether states, companies, NGOs or individuals, to make use of the tools we have to fix things, and reward them for doing so.

Anders Sandberg is Senior Research Fellow, Future of Humanity Institute, University of Oxford, Senior Research Fellow, Oxford Martin School and Ethics and Value Fellow, Reuben College. He will be taking part in the debate on A Radical Step to Gender Equality, alongside radical author Mary Harrington and post-socialist studies Kristen Ghodsee.

SUGGESTED READING Hacking Love Isn’t Cheating By Anders Sandberg  

Can algorithmic systems ever capture human complexity?  Nearly a century ago, Godel registered the incompleteness of even the most beautiful mathematical systems, let alone venerable and mutable words. Yet, today 'automagical' AI (Google's term) presupposes a direct link between formal language systems and the world, including our inner lives. But can consciousness and complex experience be modelled syntactically with total accuracy?  If not, what happens to elements that can't be fathomed within algorithmic systems? Are they dismissed as unreal, superfluous? (like being trapped in a novel by Philip K Dick...) Also: who is in charge of the formal settings of this online (and, increasingly, offline) reality - and what do they want?
