Called "mini-brains" in media reports, they are referred to as "cerebral organoids" by the scientific community, which uses them to research how the brain works, and for drug testing.One Australian firm, Cortical Labs, in Melbourne, has even developed a system of nerve cells in a dish that can play the 1972 sports video game Pong. Although it is a far cry from a conscious system, the so-called "brain in a dish" is spooky as it moves a paddle up and down a screen to bat back a pixelated ball.

Some experts feel that if consciousness is to emerge, it is most likely to be from larger, more advanced versions of these living tissue systems.Cortical Labs monitors their electrical activity for any signals that could conceivably be anything like the emergence of consciousness.The firm's chief scientific and operating officer, Dr Brett Kagan is mindful that any emerging uncontrollable intelligence might have priorities that "are not aligned with ours". In which case, he says, half-jokingly, that possible organoid overlords would be easier to defeat because "there is always bleach" to pour over the fragile neurons.

Returning to a more solemn tone, he says the small but significant threat of artificial consciousness is something he'd like the big players in the field to focus on more as part of serious attempts to advance our scientific understanding – but says that "unfortunately, we don't see any earnest efforts in this space".The more immediate problem, though, could be how the illusion of machines being conscious affects us.

In just a few years, we may well be living in a world populated by humanoid robots and deepfakes that seem conscious, according to Prof Seth. He worries that we won't be able to resist believing that the AI has feelings and empathy, which could lead to new dangers.

"It will mean that we trust these things more, share more data with them and be more open to persuasion."On the other side of the ledger, the tariffs on metals and car parts - which are unaffected by this ruling - brought in around $3.3bn (£2.4bn), based on rounded figures.

And the biggest source of tariff revenue for the US in the period was from tariffs imposed on China dating back to Trump's first term in office, which raised $23.4bn (£17.3bn). These are also not affected by the court ruling, as they were not justified by IEEPA.However, this is a backward looking picture - and the new tariffs were expected to raise considerably more revenue over a full financial year.

Analysts at the investment bank Goldman Sachs have estimated that the tariffs the trade court has struck down were likely to have raisedIn terms of the overall impact on Donald Trump's tariff agenda, the consultancy Capital Economics estimates the court ruling would reduce the US's average external tariff this year from 15% to 6.5%.
