I should say right away that I am very much a cryptocurrency sceptic. My judgement is that the dangers of cryptocurrencies do not outweigh the benefits. Cryptocurrency can interfere with governments' ability to fight recessions with monetary policy. When people are using privately created money rather than ordinary money, the money supply is beyond the government's control, and monetary policy can no longer be conducted.

There are two key features of blockchain that make it, potentially, a very useful technology from an economic perspective. First, the data about transactions are posted on many public sites thus giving these data an immutability that makes disputes easy to avoid. Second, although the data are in some sense public, they can be encrypted so that a particular party learns only those aspects that she needs to know.

We believed, and took on board the promise of growth, that it would even things up again, that it would clean up after itself, and that actually was a panacea to many of our economic ills. Yet, all the evidence has shown us that growth does not even things up- some of the richest countries in the world are becoming immensely unequal and we have seen that growth certainly doesn't clean-up after itself.

The economy is a subset of society, it's a social construct. It's entirely created by humanity- by the way we interact with one another to meet our wants and needs and human society itself is embedded in the living world, we are part of nature whether we like it or not- and we have to respect the rest of nature.

What's unnerving is that when students learn about this character (rational economic man), over time they begin to value self-interest and competition over altruism and collaboration. These models are performative. When we say rational economic man, we become more like him. Who we tell ourselves we are, shapes who we become…

Economics depicts humanity as a character called rational, economic man. I'd say he has to be a man- he has no dependants. He's a man standing alone with money in his hand, ego in his heart, a calculator in his head and nature at his feet. When we show-up, we're told that we're competitive and self-interested, the traits of the market.

GDP only catches a slice of the value that we value. It captures what goes on in the market, the financial value of goods and services sold in an economy over a year. In the boxing match between free market laissez-faire capitalists and state loving socialists the economic debate ignored the household – which is expected to provide the food, do the cooking, washing, cleaning, sweeping, education, look after the sick and elderly, yet is completely missing from GDP.

Until the Wall Street Crash of 1929, the economy had been measured in tonnes of grain and steel, and because of the crash- economists and politicians decided they wanted some grip over the scale of output of the economy- so they turned to a brilliant young scientist called Simon Kuznets and asked him how they should be measuring economic output. His answer was published in 1930s- he figured out a way to add-up all the tonnes of grains and steel and create a national income figure. He gave the caveat that it would scarcely be taken as the measure of welfare of a nation because it didn't include all the value created in a community, all the unpaid caring work at home, and only measured what was sold- not what was used-up!

We don't always see change and activism from the perspective of what we're giving, it's too often about taking things away… Don't eat that… don't do that… don't drive that car… we have to reframe and rethink. Imagine if we told people we could give them the universe back, it's a beautiful gift- but also allows us to save energy, birds, insects and more.

We have turned life into a business model- and have somewhat forgotten the reciprocity we have with nature rather; we just see it as a resource. We have maintained societies for thousands of years based on a reciprocal relationship with nature, and we need to get back to that and need to have respect for our fellow earthlings rather than seeing them as products.

In the 21st century, there are cameras everywhere except for where our food and energy come from, and where our waste goes. We are the most powerful species in the world, but we remain blind to the fundamentals that allow us to survive. How are we blind to our life support system?

We're outnumbered by bacteria 1.3:1, we're slightly more bacteria than we are human. We're also stardust. We are also 60% water, and that water in our bodies is billions of years old; it's been the clouds, the bottom of the sea, waves, streams and everything in the cycle. At an atomic level, 98% of the hydrogen in our bodies came from the bigbang. We're incredibly ancient beings, perhaps we should see ourselves as aliens!

Our senses allow us to perceive, but they're incredibly limited. Science sees far beyond our human blind spots, and the reaches of this 'bubble' our senses create for us. When you're in a bubble, you inhabit a form of fictional reality, and we've seen the dangerous consequences of this in financial bubbles, stock market bubbles, real estate bubbles… If you're not paying attention reality comes crashing in.

The rest of the world sees us as the country who had the biggest empire in the world, we don't. That creates a gap in understanding.

White people have nothing to fear from understanding their history- they're not responsible for it. It's like having therapy… it's understanding our past behaviours so that we don't repeat them. I think we need to face up to our imperial history for the same reasons.

The idea that if you are proud to be British you need to be proud of British history is nonsensical. Does it mean you have to be proud of all of history? Of slavery? Of abolition of you? Or me? Or Lenny Henry? You might as well be proud of biology or jelly. It makes no sense…
