Luxury retailers want taxpayers to fund a 20% tax break for foreign tourists. They paid consultancy Cebr to claim this will raise £2.6bn for the UK. That convinced Sadiq Khan and Kemi Badenoch. But it's false: a free lunch. Four basic errors mask a £600m loss. Thread:

A story in alt text.
Inciting incident: A large confused orange spaniel discovers the love of his life, a tabby cat, asleep on a pile of blankets, on a bed. Dramatic tension: The spaniel looms affectionately over the cat, who has just opened bright green eyesCrisis/resolution: the spaniel immediately remembers the cat is the scariest creature he knows and il fiche le camp tout suite. All the cat has done is raise his head and Disapprove.Fin: The cat, with ears set to reverse disapproval, relishes his solitude.

I could quote pretty much this entire article by @mjrobbins.com on the bizarre psychology of the AI apocalypse freaks, but you should just read it instead. Such a relief to see someone express my feelings so eloquently. martinrobbins.substack.com/p/the-ai-apo...

Confident in my ability to properly tennis, I take the court. I smile at my opponent. Serena does not return the gesture. She'd be prettier if she did, I think. She serves. The ball passes cleanly through my skull, killing me instantly

Can’t eat a sandwich until you subscribe to sandwiches. Can’t eat today’s sandwich until it has applied daily sandwich updates. Sandwich now has adverts even though you paid for ad-free sandwich. Can pay again to have less sandwich adverts. Now you can eat the sandwich, but it’s smaller.

I wish more people would address this as an executive problem. No logging, no moderation, no observability, ... Palworld has more security. For decades people (like me) could cause entire outages in entire regions. Jail or fired if I did. In most of these scenarios, some mechanism should stop me.

As someone who majored in applied maths (essentially algorithm design) and computer vision (essentially "teach a computer to interpret a picture like a human but better"), yeah, all of this. On top of everything else LLMs are making the "AI" research field poorer

Will keep boringly saying this (no disrespect to OP): it's not a health surcharge. It's not hypothecated to the NHS; you can't choose not to pay it and thereby eschew healthcare. You could equally call it an education or roads surcharge. It's using the NHS's sanctified status to rip off immigrants.

One of the key problems with AI is that the AI bros and their behemoth companies have absolutely no governance or guardrails. It's not that the AI is conscious or going rogue or whatever. It's that it's run by feckless arseholes. www.ft.com/content/2c34...

One of those things that at first sounds like an explanation and then leaves you with a whole load more questions than you started with www.ft.com/content/e070...
A military aircraft entering "spurious" flight data into the UK's air traffic control system
led to an outage that caused thousands of planes to be grounded and unleashed a crisis that threatens to topple the head of the agency.
