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.

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 […]…
MiCA’s Global Ripple Effect: How EU Regulation Is Shaping Crypto Licensing Worldwide
Why We Need to Talk About This When the European Union decided to take the crypto bull by the horns in 2023, most of us thought it would just be another bureaucratic exercise in making things complicated. But here’s the thing, the MiCA regulation (that’s Markets in Crypto-Assets, if you’re wondering) has turned out to…
How VR Memory Tourism is Revolutionizing Dementia Care in Nursing Homes
Why This Matters More Than You Might Think When I first heard about virtual reality therapy being used in dementia care, I thought someone was having me on. VR headsets? For elderly people with memory problems? It sounded like someone had confused their gran’s care home with a gaming convention. But here’s the thing. I…
You Could Soon Own a Slice of a London Building (And No, I’m Not Talking About Timeshares)
When I first heard about the UK’s Digital Securities Sandbox, I thought someone was having me on. The idea that you could own a fraction of a Mayfair office building the same way you might own shares in Tesco seemed, well, a bit far-fetched. But here we are in 2026, and it’s actually happening. The…
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…
That WhatsApp Code You Didn’t Request? I’ve Just Had One Too
The text arrived out of nowhere. “Your WhatsApp account is being registered on a new device.” I hadn’t touched a thing. No new phone, no new tablet, no fiddling about with settings. Just sitting with a cup of tea. If you’ve had one of these, you’ll know the feeling. A little jolt of panic. Has…
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.
