PLAIN-ENGLISH TECH WRITING · SINCE 2025
Technology, explained by someone who remembers when wireless meant a really long cord.
Smartphones, smart speakers, AI, crypto and the bits in between — written for people who want to use the technology, not just put up with it.
- No hype. No doom-saying.
- No get-rich-quick schemes.
- No jargon without a translation.

Are We Really Under Attack From Lab Escaping AI Systems? What’s The Real Truth?
Every few months the internet decides the machines have finally turned on us. AI escapes the lab. AI goes rogue. AI hacks a company. Usually there is a red-eyed robot picture and a quote from someone who has watched Terminator more recently than they have read a research paper. Except this summer the headlines were […]…
Google’s latest AI weather model gives you no excuse to forget your umbrella
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…
The EU AI Act: What This New Rulebook Means for Your Website
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? Then I looked at the calendar. The first rules that touch ordinary website owners started applying on 2 August 2026, and a week…
ChatGPT Remembers You Now. Do I Need to Worry About That?
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 Feel a Bit Awkward)
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. That’s roughly what just happened in the world of mathematics, and the people who do this for a living are still trying…
The Classified AI: Why Governments Are Testing Advanced AI Systems in Secure Environments Before Allowing Commercial Deployment
When I first heard that governments were locking AI systems away in secure facilities before letting them loose on the public, my initial thought was, “Brilliant, another thing for conspiracy theorists to obsess over.” But here’s the thing: this isn’t some dystopian science fiction plot. It’s actually rather sensible, like test-driving a car before you…
About the writer
Hi, I’m Walter.
I’ve lived through party lines, Betamax, dial-up and the day my VCR finally stopped flashing 12:00. These days I write about cryptocurrency, artificial intelligence and the everyday technology quietly running our lives.
I have no financial relationships with the companies I write about. Nobody’s paying me to recommend their wallets, platforms or hardware. I’m just a sensible person who figured these things out and reckoned other sensible people might want to as well — without the hype, the jargon, or promises of Lamborghinis and robot butlers.
“If you can figure out how to set the clock on your microwave, you can understand cryptocurrency and AI.”

A word on the wild west
The golden rule hasn’t changed since door-to-door salesmen.
If someone promises miraculous results, demands you “act now”, wants remote access to your computer, or asks you to send cash to fix a problem, your scam detector should be louder than the fire alarm.
The technology isn’t the enemy. It’s a tool. Your job is to stay informed, sceptical of outrageous claims, and take the genuinely useful bits at your own pace.
Your tech safety checklist
- Never share passwords or personal information by email or phone.
- Use two-factor authentication whenever it’s offered.
- Keep your software updated — those reminders really do matter.
- If something feels wrong, trust your instincts. They’ve served you for decades.
- Legitimate companies don’t create artificial urgency or use scare tactics.
