We live in frightening times. Wars in Ukraine and Gaza could widen, the polar ice caps are melting, and even some scientists developing artificial intelligence systems are worried about unleashing a monster. But those fears all pale in comparison to what really gives Americans the jitters. The calamity that worries them above all else is a total economic collapse in the US. The Pentagon's four legged robot dogs may offer a glimpse of what killer machines will look like An economic meltdown is the top fear for a third of respondents.

They believed that global population growth, industrialisation, pollution, food production and resource depletion would inevitably lead to economic collapse during the 21st century. They believed that global population growth, industrialisation, pollution, food production and resource depletion would inevitably lead to economic collapse during the 21st century. They were concerned not just about environmental issues, but also about economic ones: namely, that increasing population growth would lead to overconsumption and ultimately cause a collapse in resources (the so-called "Malthusian trap").

I am spending my last weeks on thinking about climate actions, sustainability and economical aspects of these. I listened to a lot of podcasts about these topics, and I have tens of notes from these podcasts. I decided to express my ideas about this topic. But no, it is not my turn to spread the ideas. Only thing I wrote for this article is headline and a couple of keywords.

A woman living in Kenya's Dadaab, which is among the world's largest refugee camps, wanders across the vast, dusty site to a central hut lined with computers. Like many others who have been brutally displaced and then warehoused at the margins of our global system, her days are spent toiling away for a new capitalist vanguard thousands of miles away in Silicon Valley. A day's work might include labelling videos, transcribing audio, or showing algorithms how to identify various photos of cats. Amid a drought of real employment, "clickwork" represents one of few formal options for Dadaab's residents, though the work is volatile, arduous, and, when waged, paid by the piece. Cramped and airless workspaces, festooned with a jumble of cables and loose wires, are the antithesis to the near-celestial campuses where the new masters of the universe reside.

The age of the robot has been predicted for decades. First used as a term to mean automated labor back in the 1920s, and popularised in the classic 1927 slient movie Metropolis, they have been a regular feature of science fiction ever since. The fact that robots and science fiction go hand in hand – and that predictions that we will soon have robot helpers being regular features of future-gazing since the 1930s – has meant that the idea of robots becoming a central part of our lives have become so familiar that we've come to ignore them. Yet robots have been a reality in manufacturing for decades, having become cost-effective production-line solutions by the 1970s. The Roomba – an automated vacuum cleaner that is perhaps the most famous domestic-helper robot – was launched back in 2002, and has sold more than 10 million units worldwide.
