I'm still amazed at how many people think AWS Lambda is basically kubernetes.

Have been having frustrating conversations today. It made me realise how poorly understood LLM usage in tech actually is. Most people still seem to be at the stage of "I'm in a repo and I direct the AI to fulfill a feature request/bugfix".

One of the hardest things about being progressive is knowing the limit to inequality. For communists, it's easy. There'll be no inequality. For neoliberals, it's also easy. There's no limit to inequality. But most people live somewhere between these positions, never sure where to draw the line.

I've realised that my brain has so much more context than 280 characters can handle. When I say stuff, there's usually 47 thoughts unsaid. But what I'm realising is that this isn't the normal way people think. It's an ADHD thing in some ways. My brain gets to the conclusion very fast.

This is why you should be **very careful** using these models. Your prompts and content you upload (unless you opt out where you can) *WILL* BE USED AS "TRAINING DATA". "TRAINING DATA" Good grief. I genuinely despair of people using these tools without opting out. Auto opt out *now*.

If I've learned anything about solving problems in Northern Ireland in the past few decades, it's that people outside Northern Ireland think it's simple and people inside Northern Ireland think it's impossible.

I'm going to disagree. There's a difference between control and accountability. The way that the AI is being used is uncontrolled. It's not OpenAI "doing" it. And it's not OpenAI "directing the AI to do this". But OpenAI is responsible for whatever it does.

The Stanford Kitchen Experiment: Where a robot is put into an almost immaculate kitchen and told to tidy it. It looks around wondering what the humans are talking about, and performatively "tidies the kitchen" until the humans tell it to stop. Robot eventually goes mad.

If you can write, AI allows you to reshape your world. We've become so reliant on tech that it's now everywhere and businesses rely on it all the time. Tech is everything from email to phones to business accounts to marketing to getting your food delivery. It's already changed everything.

I don't think people understand how *stable* political leadership is a lot to do with *not* following public opinion and is a lot more to do with consistency. Thatcher and Blair did it. Two of the most hated political figures in Britain. But largely brought political (not economic) stability.

Counter argument: Make the data open by design from the outset. And maybe there's a good argument to modify the scientific process in an age of AI. Science is not static and neither is the advancement of knowledge. I imagine there were arguments against using computers in research 60 years ago.

This is my worry for the Green Party. The bump started as a protest vote against Starmer from the left and gained a lot of momentum. It was why Starmer going right to combat Reform was strategically inept. Labour doesn't own the left but it does have weight. The budget will determine how much.

I would really like to see Zack get elected. I do think Labour are taking a lot of support for granted and have neglected their progressive wing for a long time. No party is perfect including the Green Party but I have more faith in the Greens than Labour now.

Having to explain to Green Party people that to solve the issue of data centre water usage, you just have to build some reservoirs and they will still complain about water usage of data centres. It's almost nonexistent. Especially in the UK.

What's amazing to me is that the politicians start jumping when AI companies claim an existential threat... But have been dithering on climate change for nearly 40 years. One is a guaranteed existential threat, and the other has very little evidence beyond fearmongering.

Good news! I made the case for banning adverts for high-carbon products back in 2020. It was important then and it’s even more crucial now. Huge respect to @adfreecities.bsky.social for their years of campaigning, and to my @bristolgreenparty.bsky.social council colleagues for making it happen 👏

Huge result as Bristol council approves ban on ads for fossil fuels and other polluting products and services.Screenshot of second page of Instagram post by Adfree Cities: In a massive win against polluting advertising, Bristol City Council has introduced restrictions on ads for SUVs, fossil fuels, airlines, cruises and ultra-fast fashion on council-owned and sites. The policy aims to make rim for the promotion of more sustainable forms of transport, travel and holidays.

This is why the climate crisis is not getting solved at this point. Internally the goal is market share, not a livable planet. Until that changes these companies are, at best, unreliable partners regarding the climate crisis and at worst actively harmful. It's not the workers. It's the system

The mobilisation of the Greens for this by-election is actually quite incredible. I originally gave Zack around 25-30% chance to win. That's gone up. I think Labour have a real fight on to retain this seat.

One advantage of the huge sums donated is that it destroys the "anti establishment" narrative. Reform are the party of the rich. No question. Anybody that thinks that they are interested in the working class are just wrong. But the issues they are tapping into are real.

I've just had to get a new smartphone. I've always just bought a "good enough" phone. But prices have jumped and the last phone I got had a poor camera. Most phones now will have enough power to do the things I want. The biggest thing I realised I want is a good camera. Nothing else matters

25 years later and The Onion’s ParentCorner 9/11 explainer from immediately after the attack is a better understanding of the threat environment than the one produced by the U.S. government.
An Onion article titled “Talking to your child about the WTC attack,” which is filled with real good info.

This excellent piece is worth a read. I'm so frustrated with the data centre debate. Almost everything gets solved with decarbonising the grid and mandating water use **if it's even needed** using closed loop systems. The US political debate doesn't transfer here in the way many think.

Oh good grief. Data centres don't really create jobs and certainly not in the local community. The capacity and services they enable are where the jobs come from. And sovereign capacity and capability is important for things like national security. So it's not just a "number of jobs" equation
