"The very foundation of every AI startup is economically broken. The majority of them sell some sort of “deep research” report feature that costs several dollars to generate at a time, and many sell some form of expensive coding product, tool-based web search features, and many other products that exist to keep a user engaged while burning tokens, all without explaining to the user “yeah, we’re spending way more than we make off of you, this is an introductory rate.”" https://www.wheresyoured.at/the-subprime-ai-crisis-is-here/

"The more I think about it, there are strong arguments for being less efficient these days. It feels like every advert at the moment is generally geared around the idea of saving you time. Which I understand conceptually, as no one feels like they have enough, but I disagree that the solution is (...) AI in general. The elephant so often in the room is, what you’re going to be doing with all this newly free time beyond the vague notion of having ‘fun’?" https://kiosk.substack.com/p/when-in-rome?triedRedirect=true

"As the benefits of Scotland’s financial system became increasingly obvious, it was soon regarded with envy elsewhere – especially to the south. The core elements of its banking were extended by legislation to the rest of the UK in the 1820s, and there were attempts in the 1850s to do the same for its debt-enforcement provisions, though these failed to get voted through" https://www.ageofinvention.xyz/p/age-of-invention-why-scotland-succeeded

"Our suggested guidance for navigating this current transition is to make a culinary analogy: vanilla extract, a common ingredient in most sweet recipes famous for its nearly universally appealing scent. Ingestedby itself, vanilla extract is usually considered extremely unpleasant, but its addition in small amounts is widely regarded as improving and enhancing the other flavors of the dish, even when it cannot be differentiated from them...." https://arxiv.org/pdf/2603.26524 #AI
