Diamond prices are down 60% since a 2011 high, and they are still falling. It's not all down to lab-grown diamonds, demand is down too, especially in China.

No one can lab-grow gold yet, so its rarity and scarcity protect its value, but that will end too. It's just a question of when. China launched an asteroid touch-down mission this week, which will make it the 4th country/region to do so, after Europe, the US & Japan.

How soon will it be feasible to mine asteroids? Who knows, but a breakthrough in space propulsion might mean the prospect happens quickly when it does. It's possible gold has twenty years or less of being high value left.

One of the most persistent biases in commentary on AI is many people's assumption that Silicon Valley VC-funded efforts are its main driver. But all the evidence points to something bigger than them - Open-Source.

Alibaba, the Chinese company that developed QwenLong-L1 isn't making their AI open-source out of the goodness of their heart. They get the benefit of lots of free workers improving it, and they also get to undermine their competitors. Many of the open-source AI are Chinese. It's possible China may be coordinating their efforts on a national scale, as a tit-for-tat retaliation measure responding to the US trying to weaken Chinese AI.

The global effect is the decentralized dispersion of AI technology with no one company or country dominating it - in the long run that will be its biggest outcome.

Canada is heating up at twice the global average thanks to climate change. The fire seasons of 2023 and 2024 were the worst two years for wildfires in Canadian history - now 2025 looks set to beat their record.

Canadian wildfire smoke carries PM2.5 particles that can travel far into the U.S., worsening air quality in the Midwest, Northeast, and Great Lakes regions. These fine particles penetrate lungs and bloodstream, causing inflammation, lung damage, and higher infection risks. Children, the elderly, pregnant individuals, and those with heart or lung conditions are most vulnerable. Long-term exposure can worsen asthma, heart disease, and increase premature death risk.

Tough luck for Americans that they're living in the age of 'drill baby, drill' when the fossil fuel industry comes first, not them. As Lord Farquaad would say "Some of you may die, but it's a sacrifice I am willing to make".

The rocket is quoted as having a cargo capacity of ten tonnes. How much do they think each launch will cost? If it's $1 million, then that is $100 per kg. Is there anyone willing to pay that much money for same day delivery?

There are four other Chinese companies who say they are close to launching reusable rockets too, and expect to launch in 2025/26 - iSpace, LandSpace, Deep Blue Aerospace, Galactic Energy - though the last is only talking about a reusable booster.

Also interesting - the publicly disclosed funding for this company is less than $100 million. I'm assuming they had more they did not disclose. If they managed to do this for $100 million, that seems very impressive.
