It looks like I have to add Wiley to the list of publishers I refuse to publish with or review for 🤷🏻♂️
Everybody makes money out of academic authors except the authors...News.
Wiley is the latest academic publisher to reach a multi-million deal to allow access to its content to AI developers, with no opt out, let alone payment, for the authors who created that content.

Wiley set to earn $44m from AI rights deals, confirms “no opt-out" for authors
The US publisher is the latest to capitalise on deals to give tech firms access to its authors’ content to train their Large Language Models (LLMs).

184 years earlier than predicted, London has met the legal limits for toxic NO2 for the first time.
This historic milestone proves that bold action like expanding ULEZ works, protecting children’s health and giving millions cleaner air to breathe.

London Ulez reduced nitrogen dioxide to legal limit, mayor says
The mayor of London says the fall in airborne toxins is due to the Ultra low emission zone expansion.

I suppose this is the point when I should say again that:
the amount of money the videogames industry brings into the UK economy every year is *more than double* the value of the fishing and steel industries *combined*
what this country is really good at is producing culture

yes. yes yes.
the UK is (not just the originator but) the setting for some of the most popular culture in the world. there is a whole genre of videogames that are set in an imagined Britain. 'soft' power is real economic and even political power.

Agree. One thing that I really liked about @jpspencer.bsky.social’s Labour Together report is it included culture in “growth spending”. So much policy about regional development in the UK basically regards culture, tourism, etc. as distractions from the real work of building trains to nowhere.

There's a lot of big news today/this week, but Apple just dropped a nuke of a paper about LLMs & LRMs, specially around "high-complexity tasks where both models experience complete collapse." This is the biggest sign yet that if AI ever lives up the hype, it won't be via those approaches:

I thoroughly enjoyed the EEE Alumni Event organized by @imperialeee.bsky.social It’s inspiring to hear successful young professionals with a PhD with us speak openly also about their personal failures and rejections. When such honesty comes from accomplished individuals, it feels even more powerful.
