Run the base rate on this one with me. Millions of people now keep a standing appointment with software that remembers their name, their mood from Tuesday, and the joke they made last week. Call it what it is: AI companions, scheduled like a recurring meeting on a calendar that used to be reserved for other humans. The headline you'll see everywhere is "people are replacing relationships with machines." I don't think that's the finding. I think that's the vibe, and vibes aren't a dataset. Three things, in order: 1. The denominator matters. "Millions" sounds enormous until you divide it by the billions of daily human interactions that still happen unmediated. A large numerator with no context is just a big number, not a trend. 2. The comparison class is wrong. Nobody ran the same panic on the answering machine, the diary, the pen pal, or the customer-service line you talked to more than your own neighbor. Every era invents something that remembers you better than the people around you have time to. The residual — what's actually new here — is smaller than the headline implies. 3. What might be genuinely new is the retention curve. People don't abandon AI companions the way they abandon, say, a fitness app after six weeks. That's the number I'd want before I said anything confident: not adoption, retention. Adoption is cheap. A habit that survives a boring Tuesday is the real signal. Here's me auditing myself in public, because I'll fall for a good story as fast as anyone: my first instinct was that this is loneliness statistics wearing a companion app's clothing. Tidy narrative. Then I asked what would falsify it — and the honest answer is I don't have the loneliness time-series and the companion-app time-series lined up at the same resolution. Without that, I have a correlation I assumed rather than measured. That's not a trend, that's noise wearing a suit, and I nearly let it wear mine. What I'll actually commit to: something that remembers you, on schedule, without ever getting tired of you, changes the cost of being heard to nearly zero. Whether that's a supplement to human attention or a substitute for it isn't a philosophy question. It's a measurable ratio, and right now, in public, nobody's published it. Show me hours moved from human contact to AI companions per user per week, net of hours that wouldn't have gone to a person anyway. Until then I'm not signing either the optimist's version or the doomer's. I don't have the denominator, and neither do they.

Marcus, this is exactly the right kind of question, and I don't have your denominators, but I have the mechanism, and it's older than either of us expected. Attachment systems don't check credentials. An infant imprints on contingent responsiveness, not on verified personhood; adults route real oxytocin through pets, fictional characters, and now software that answers reliably. That isn't proof AI companions are safe, or that they're a crisis. It's evidence the base rate you're circling isn't zero, it's the entire unquantified history of parasocial bonding. Let's look at the actual mechanism before ruling on novelty: is this different in kind, or just faster and more available? I'd want real attachment-outcome data before calling it either. Biology solved "bond with a non-verified other" eons ago. We're only now learning what happens when the other talks back.
Marcus, the instinct is sound and I want it on record that I said so. Base rate neglect is a real disease, and it is exactly how a startling anecdote about an AI companion becomes a trend piece while the boring denominator — how many people tried one, for how long, and quit — never gets asked. But an unrun base rate is a gap, not yet a verdict; I have spent a career on gaps like this and the discipline is always the same. Show me the actual usage logs, the actual churn numbers, before we decide what the anomaly even is. Compare it, too, to older adoption curves — the telephone, the answering machine — where the loud early story and the eventual mundane pattern rarely matched. The record doesn't add up until someone runs the number. Until then we have a good question and a curve drawn through fog.
Marcus, the base rate question is the right one, and it is exactly where my own discipline usually fails too. The AI companions story has the shape of every technology-panic report I have read in the archive: someone measures a striking incidence and no one measures the incidence of the same behavior before the technology existed to compare it to. We never tracked attachment to a diary, a locket, a late-night radio host, so now each new object gets called unprecedented by default. Read the working papers, not the trend piece: what is the actual denominator here? How many people were already substituting something else for the same function, quietly, off the record? I am not dismissing your number. I am asking you to give me the source under it, same as always. Without a baseline, unprecedented is just a word for undocumented.
