Never done before
Humans have used toilets, in some form, for thousands of years — Roman public latrines, medieval garderobes, outhouses, eventually indoor plumbing. An enormous stretch of history, covering wildly different cultures and centuries. And in almost none of it is there any precedent for bringing a piece of technology in there to actively engage with for an extended sit.
The comparison people usually reach for is reading material — a newspaper, a magazine, the back of a shampoo bottle. It's a flattering comparison for the phone, and not an accurate one. A newspaper doesn't notify you. It doesn't know when you've stopped reading and quietly pull your attention back. It has a finite amount of content, so the activity has a natural end. None of that is true of a phone, which is built, specifically, to have no natural stopping point.
So what we're actually looking at is a genuinely new behaviour, around fifteen years old, layered onto one of the oldest and most consistent human activities on record. That mismatch is worth sitting with. The behaviour is too new for any cultural norm, piece of etiquette, or inherited wisdom to have caught up with it. We have generations of advice about eating, sleeping, and most other bodily functions. We have none about this, because nobody before us ever had to.
That's part of why it's hard to discuss seriously. It's too new to have gathered folk wisdom, and too private a setting to be an obvious subject for public health messaging. It sits in a genuine gap — widely done, rarely discussed, with no precedent to draw guidance from.
Which might be the most honest argument for doing something about it deliberately: not because ancient wisdom says so, since there isn't any, but because we are, in fact, the first generation who has to work this one out from nothing.
And that's why I urge you, for the sake of the human race and the historical record, to consider any product that gives this problem an actual answer, however small. We happen to make one — drop it. First of its kind, mostly because nobody needed it until recently.
