As one UK university after an other goes into “restructuring”, a euphemism for hollowing out by administrators, you never hear the phrase “fiduciary duty”. It is clear that these people see the university primarily as a business that they can leave behind. Lost is the idea that they are […]

It boggles my mind how many social protests and actions are organised, advertised, and reported entirely on Meta (esp Insta). Our union (Equity) are wedded to it and it baffles me.

Gave my third OTZ lecture today to our Life Science students. We estimated the mass of the atmosphere, worked the stock (the mass) of CO2 present, and from there the mass of annual emissions and thought about it in relation to earth's population.

Managed to sneak my way in (late) to Michael Mann's "Science under Siege" talk at the Crick today. Very good and with constant reminders that there is everything to fight for - doom is a strategy by those who want you to give up, not a future.
Michael Mann in front of a slide with a picture of Sam Gamgee from the Lord of the Rings saying "There's some good in the world, Mr Frodo and it's worth fighting for. "

People who find LLMs useful when "used correctly" don’t understand that they manage to use them correctly because they spent 20 years of there life learning their craft without LLMs. LLMs is the only tool where the less you use it, the better you become at using it.

& here is your regular reminder that the most important sector full of jobs AI have eliminated wasn't by substitution but by eliminating revenue from newspapers. I've heard it suggested that Google's way they found to fund "the mind of god" is the cause of democratic backsliding. 3/3 #AIEthics #FoW
news paper revenue building steadily though very nonmonotonically 195- until 2000, then just crashing exactly as google revenue rockets to the same level. Facebook comes in around 2008 and gets up to about where newspapers plateay around 2018, graph goes to about 2020. BTW can't find the carpe diem blog, it used to be easy to search for, guess someone doesn't want you to see this.
