The irony isn't lost on us.
I am filming Mark Boyle with my iPhone - so typical of the technology he has turned off, and away from, forever.
Mark is sat in the window seat of a cosy wood cabin on a smallholding in east Galway.
The Donegal man built his home with his bare hands.
He has also learned how to make fire, grow his own vegetables, collect water from the spring, forage and fish.
As I look around this warm and welcoming space, my endeavours with my phone suddenly seem rather inadequate.
"The cabin is made from straw bales, which is a great insulator, and wood from the landscape around me. It's mostly windfallen timber. My home is completely off-grid, as there's no running water, no electricity and no gas. I don't have any internet or a mobile phone. I don't have a washing machine, light bulbs, a clock or any of the things which for most of my life I took for granted," he tells me.
In their place, he has discovered "an elemental life", one governed by the rhythms of the sun and seasons.
Indeed, spring sunshine is now flooding into the cabin, turning the wood a variety of hues.
While I take photographs, Mark turns his attention to writing a letter.
No email, means he is using pencil and paper - his modus operandi for several years.
During that time, Mark has written several articles on his life without technology for The Guardian newspaper.
Each article was written by hand, often by candlelight, and posted to an editor at the newspaper, who transcribed it to go online.
"I definitely think I'm the only writer posting hand-written articles to The Guardian. Before me, they probably hadn't received a hand-written article for 30 years!" laughs Mark.
The articles have become a book, Mark's fourth.
As "the moneyless man", he has previously written about living without cash for three years.
He says his decision to ditch technology "has not been about saving the world, but about savouring it".
Mark takes me fishing on Lough Derg, where he hopes to catch a pike for dinner.
As he stands at the end of the pier, I scan the notifications on my phone.
"When we're living in this modern world, we're often giving up our connection with nature and our connection with people. When we're staring into our phones and our screens, we're not really aware of the life around us. One of the many benefits of this way of life is that I've completely missed Brexit. I hear the odd word about backstops, fake news and that kind of thing. But I wouldn't know any of the details, thankfully," he says.
By now, the sun is heading towards the horizon and my phone battery is fading.
But Mark appears fully charged.
"I've lived with tech and without, and I know which one brings me most peace and contentment," he says, as we say our goodbyes.
