The far right holds power in the US, inflaming tension along racial lines. ICE agents terrorise the streets, while Black history is erased from school curricula. In the UK too, Nigel Farage’s far right party Reform is on the ascendancy, riding a tide of anti-immigrant sentiment that he himself helped to stoke.

Our guest on Downstream this week is Professor Kimberlé Crenshaw, civil rights advocate and legal scholar. Crenshaw is known for coining the term ‘intersectionality’ to describe the ways different forms of discrimination combine or intersect, and is a leading figure within the field of Critical Race Theory. Born into segregation, her new memoir Backtalker (2026) tells her life story, tracking 60 turbulent years of American history in the process.

How have the forces of race, class and gender shaped Crenshaw’s own life? What is Critical Race Theory – the academic field Crenshaw founded – really about? Was Kamala Harris’ presidential campaign a failure because she was a weak candidate, or because she was a victim of the forces of misogynoir? And in these times of rising fascism, should progressives put their efforts into tackling inequality based on race, or class?

A wealth tax on the very richest people in our society has never been more popular. Recent polling puts the plan at 90% approval, a figure almost unheard of for any policy proposal.

This week’s guest, Gabriel Zucman, is a French economist who has done the most comprehensive work on what such a tax could accomplish.

And he’s also a key inspiration for the UK’s leading wealth tax advocate – and friend of the show – Gary Stevenson.

AI progress isn’t slowing down. The bubble doesn’t seem to be popping. And who in power actually cares about the environmental impacts anyway?

All that is to say: AI is here to stay. And what will be its fruits? Greater control of workers or even their brutal repression, some say.

So, is there a positive future for AI at all?

Garrison Lovely is the author of Obsolete: The AI Industry’s Trillion-Dollar Race to Replace You—and How to Stop It. And surprisingly, his answer is “yes”. He told Richard Hames about the dangers of AI, and how to get off the path to dystopia.

Do Your Own Research is a new show from Novara Media about the systems that make the modern world possible.
