Dear Shabana,
I notice today that you referred to me in your speech on immigration at the IPPR think tank.
You said: “A party leader should not be on the beaches of France encouraging people to
make a perilous crossing on small boats.”
I suppose I shouldn’t be surprised especially after the hateful Labour campaign in Gorton
and Denton, but this is just the latest in a string of lies peddled by a discredited Government
who intentionally fan the flames of racism and division.
When I went to Calais, I was not there to encourage people to travel to the UK. I was there
to see at first hand the suffering your Government and successive Governments have done
in demonising migrants in a pathetic bid to pander to the base instincts of Reform and the
flawed strategy of Morgan McSweeney.
As you will know, if you even bothered to research my visit instead of taking Reform talking
points, I was there to witness the brutality of families living in tents in freezing temperatures. I
filled water tanks and picked up litter.
What that visit did do is confirm my belief that if we are to smash the boat gangs and stop
the boats, we need to offer safer and managed routes for migrants to come to this country.
Showing compassion as a politician is not a crime. In fact, we need to see much more of it.
It reminded me of a young MP who in October 2015 spent three days in Lesbos helping
migrants fleeing war-torn Syria. She posted videos on X, talked about handing out water and
croissants to refugees and food parcels.
When she returned to the UK, she wrote a very moving piece in the New Statesman. She
said “we have to work with our European partners and create new, safe, and legal routes for
refugees to get to Europe. We cannot abandon them to their fate, left as prey for smugglers
whilst risking death on the seas.”
She said “maybe we can make ourselves feel better by saying no-one is making them get on
the boats. And again, the Home Secretary is not entirely wrong when …

Dear Shabana,

Let's clear some things up around migration and remember we're talking about people's lives.

Pluralistic: Dirty words are politically potent (14 Oct 2024) – Pluralistic: Daily links from Cory Doctorow

"the fact that a neologism is sometimes decoupled from its theoretical underpinnings and is used colloquially is a feature, not a bug. [...] This is what it means for a term to enter the lexicon: it takes on a life of its own."

To be fair, he is very positive about people broadening the term. He even says it is a good think that there is a technical term that can be applied narrowly, and an intuitive term that can be used broadly, and that both coexist.

Tao: These problems are like distant locations that you would hike to. And in the past, you would have to go on a journey. You can lay down trail markers that other people could follow, and you could make maps.

AI tools are like taking a helicopter to drop you off at the site. You miss all the benefits of the journey itself. You just get right to the destination, which actually was only just a part of the value of solving these problems.

Wake up, honey! A new extension to the "maths as journeying" metaphor just dropped.

I made a philosophy cryptic crossword for our postgrad reading party last week. A few people asked about it, so I shared it with @dailynous.com, and it's now available on the Heap of Links: dailynous.com/wp-content/u...

The Promptware Kill Chain Attacks against modern generative artificial intelligence (AI) large language models (LLMs) pose a real threat. Yet discussions around these attacks and their potential defenses are dangerously myopic. The dominant narrative focuses on "prompt injection," a set of techniques to embed instructions into inputs to LLM intended to perform malicious activity. This term suggests a simple, singular vulnerability. This framing obscures a more complex and dangerous reality.

I think that he has changed directions a bit since we wrote this, focusing a lot more on the interactive version. Some but not all the same argument can be used there.
