PLAIN-ENGLISH TECH WRITING · SINCE 2025

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.

Walmart, Maersk, and IBM’s Supply Chain Blockchain Networks: Tracking Billions in Goods Without Crypto Hype
Why This Matters More Than You Think When most people hear “blockchain,” they immediately think of cryptocurrency, dodgy investment schemes, and that bloke from the pub who won’t shut up about Bitcoin. But here’s the thing, some of the world’s biggest companies are using blockchain technology right now to track everything from your mangoes to […]…
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…
Nearly 6 in 10 Brits Are Using AI to Check Their Symptoms: The Digital Doctor Revolution
I’ll be honest with you, the first time I heard that nearly 60% of Brits were typing their symptoms into an AI symptom checker instead of ringing their GP, I had two immediate thoughts. First, that’s absolutely brilliant. Second, we’re all going to convince ourselves we’re dying from something we saw on the internet, aren’t…
Older Adults Are Embracing AI Faster Than Expected
A new AARP report shows AI use among over-50s nearly doubled between 2024 and 2025, with around 30% now using some form of AI tool. Smart home gadgets — cameras, lighting — are in half of older adults’ homes. The digital gap is closing faster than people think. 🔗 AARP – 2026 Technology Trends Older…
AI Can Now Predict Alzheimer’s With 78% Accuracy, and It’s Absolutely Brilliant
When I first heard that artificial intelligence could predict Alzheimer’s disease progression with 78% accuracy, I had to sit down with a cup of tea and really think about what that means. Not just for the tech world, which gets excited about anything with “AI” slapped on it these days, but for real people. For…
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.
