While new AI tools may seem novel/unprecedented right now, there's a lot we can probably still learn about their likely effects by looking at past technological innovations.

Will have to wait and see what the final proposals are, but glad that some of the more exotic calls to mess around with the core market rules haven't been heeded.

But subsidising fossil fuels during a crisis caused by supply scarcity is a poor use of gov funds. Doubling down on electrification and clean energy (+ some targeted low-income support) is the way to go [contains quote post or other embedded content]16 Apr 2026 14:59 +0000at://did:plc:5t3gg4aaeqrnuzgxihbmbru5/app.bsky.feed.post/3mjmodn4e3k2qhttps://bsky.app/profile/stephenjarvis.bsky.social/post/3mjkoc7uuik2kWeirdly blasé piece on clothing basically coated in PFAS. Even links to a seperate article that says "Avoid textiles that advertise their waterproof and stainproof qualities but don’t claim to be PFAS-free". To say nothing of reducing the manufacture of these chemicals in the first place.

Big piece of kit that’s been cranking out a whole lot of low-carbon power for 4-5 decades. Lots of offshore wind and a proposed 1GW battery project connecting in this area too. Impressive. 🔌💡13 Apr 2026 15:15 +0000at://did:plc:5t3gg4aaeqrnuzgxihbmbru5/app.bsky.feed.post/3mjf5un766225https://bsky.app/profile/stephenjarvis.bsky.social/post/3migqsxoee22jEncountered several coffee places now where I’ve got a small iced americano and thought “hey this tastes great”.

Gonna be a day of high highs and low lows01 Apr 2026 13:02 +0000at://did:plc:5t3gg4aaeqrnuzgxihbmbru5/app.bsky.feed.post/3migqsxoee22jhttps://bsky.app/profile/stephenjarvis.bsky.social/post/3mhzh6m4sys2qI have seen lots of enthusiastic posting about what a great idea this is. And don't get me wrong, I get the frustration with electricity prices spiking so high when gas prices rise. But so far I've seen far too many half baked solutions being thrown around that don't really add up. 🔌💡 (1/12) https://news.sky.com/story/ed-miliband-tells-mps-how-he-hopes-to-cut-household-energy-bills-amid-calls-for-more-north-sea-drilling-13523989?logging_media_id=3860517616045627986_6342257167627 Mar 2026 06:05 +0000at://did:plc:5t3gg4aaeqrnuzgxihbmbru5/app.bsky.feed.post/3mhzh6m4sys2qhttps://bsky.app/profile/stephenjarvis.bsky.social/post/3mhy5itp6622sI would say the spread of sports betting in the US is a slow motion disaster, but it has been anything but slow motion. Full on speed running to catch up (and surpass?) places like the UK where this has already been a long-running problem for decades.
