It's the life we're told we want, where we just shout at a device and our needs are met as quickly as the supply chain allows. Aleks Krotoski explores frictionless digital living.

But is there value in friction? Aleks hears from someone who's life depends on it, mountaineer Andy Kirkpatrick. He has a reputation for stacking the odds against himself as much as possible; long routes, often climbed alone in the worst of conditions. Back on the ground Andy also needs friction to not get complacent, accept others views without question, to keep moving forward.

Without friction we risk falling prey to what economist Umair Haque describes as the infantilisation economy. One where we are diminished by being able to have our every need met by Amazon's Alexa. And the cost isn't just to us but also to the army of digital serfs peddling about in all weathers with those trademark boxes on their backs. Its a future that was foreseen as far back as the late 19th century by the likes of Nietzsche in his descriptions of the 'last men' a humanity living the most vanilla of existences without challenge or ambition to change.

Nothing sums this up better than the food replacement industry. No time to shop, cook, chew? Get everything you need nutritionally in a drink like Soylent or Huel - all in the name of efficiency. Its a world that fascinates anthropologist Jan English-Luek who for over 20 years has been observing trends in silicon valley.

Ultimately Aleks will ask what we're saving all this time and effort for and do we ever reap the benefits? Or does it just keep us where the digital world wants us, consuming in ever more efficient ways.
