  • No “AI will steal your job” panic.
  • No magic — just a useful tool, explained.

The honest story behind ChatGPT and friends, what they’re genuinely good at, and where they confidently get things wrong.

The simple craft of writing a prompt that gets you the answer you actually wanted — not a 700-word essay you have to skim.

Spotting deepfakes, dodging scams, protecting your data, and knowing when AI is genuinely useful versus marketing fluff.

You don’t need to learn all of them. But knowing what each one is good at — and which ones are free — saves you from paying for things you don’t need.

Are We Really Under Attack From Lab Escaping AI Systems?

Every few months the internet decides the machines have finally turned on us. AI escapes the lab. AI goes rogue. AI hacks a company.

Google’s latest AI weather model gives you no excuse to

I have spent a good portion of my life being wrong about the weather. Not slightly wrong. Spectacularly, soakingly wrong. I have set off for a walk in a linen shirt because the little sun icon on my phone said so, and arrived home looking like I had been dragged out of a canal. And…

AI Can Now Predict Alzheimer’s Years Before Symptoms Appear

The Technology That’s Changing Everything We Know About Memory Loss When I first heard that artificial intelligence could predict Alzheimer’s disease before someone even forgets where they put their keys, I thought it sounded like something from a science fiction film. You know, the kind where computers become smarter than humans and start making all…

EU AI Act
The EU AI Act: What This New Rulebook Means for

I’ll be honest. When I first read about Regulation 2024/1689, better known as the EU AI Act, my eyes glazed over. Another regulation. Haven’t we only just got our heads around GDPR?

ChatGPT Remembers You Now. Do I Need to Worry About

I’ll be honest with you. The first time I heard ChatGPT could now remember our conversations, I thought of that neighbour everyone seems to have. The one who somehow knows your whole business without you ever quite telling them. Bits dropped over the garden fence, added up over months, until one day they ask after…

When AI Solved an 80-Year-Old Maths Problem (And Made Mathematicians

Imagine leaving a puzzle on your kitchen table in 1946. Then imagine, eighty years later, a computer programme sits down with a cup of tea and works it out in about eighty minutes.
