This gorgeously summarizes the problem with large language models. Granted, LLMs can be very useful, too -- but caveat emptor.

Global average temperatures are spiking, rising faster than climate models seem able to explain, and in a sane world, every country would be united in a full-scale effort to figure this out & respond. Instead the US is dismantling its scientific infrastructure.

I was surprised to see in today's ONS figures that UK goods exports suddenly rose 3.5% in Q1/25. Then I found this was almost entirely driven by a surge in UK aluminium exports to the US ahead of Trump's tariffs. This alone pushed UK GDP growth by ~0.2 ppts (out of 0.7 ppts total in Q1). Amazing.

Why are solar panels and batteries from China so cheap? High levels of automation, cheap energy, and state-of-the-art manufacturing processes. It's less about low salaries than many people think. My latest Substack: www.sustainabilitybynumbers.com/p/china-chea...

Microsoft is merging Teams and Skype. Good! Skype has always been that thing you accidentally click in a context menu. By default, they enabled anyone to find me using my email or phone number, so I turned those settings off. Why? Because otherwise, these are the messages you get.

Kirjoitan blogikirjoitusta VM:n oudosta toiminnasta yhteisöveron alennuksen suhteen: Kirjoitan koska en näe isomman kuvan käsitellyn missään mediassa, joten haluan ikuistaa ihmetykseni isommaksi tarinaksi. Mutta mieleen tulee, miksei suuret mediamme tee juuri tätä, hahmota isompaa kuvaa? 1/

Interesting piece which reveals a lot of the tech bro ignorance of government: DOGEr comes in, expects to find lots of inefficiency, is at least willing to acknowledge he was wrong unlike the hard core ideologues.

Authoritarianism functions in predictable cycles and Trump is currently laying the groundwork for using state violence to meet organized resistance. So much depends on what we do now and how we meet this moment. jaredyatessexton.substack.com/p/an-escalat...

Onpa siistiä, että SK on saanut haastiksen @timothysnyder.bsky.social'lta. Tämä kannattaa lukea, erityisesti kohta, jossa Snyder puhuu hyvinvointivaltiosta ja miten se merkitsee vapautta. Bravo jälleen @leenasharma.bsky.social !

Insightful text. If one's friends and family start to distance themselves, it might not be due to a simple disagreement; just a matter of who is right and who is wrong. It might be about how they perceive the morals and character of that individual after witnessing them express their opinions.
