On Additive and Extractive Technologies
AI Summary
Cal Newport draws a distinction that sharpens his philosophy of techno-selectionism: additive versus extractive technologies. The frame comes from a Substack post by a mother who bought her kids a retro rotary-style landline so her son could talk to his grandmothers — it became the sweetest, most unexpected daily ritual. "There's no scrolling, no distractions, no comparisons, no dopamine hits to chase. Instead he is just listening to stories, asking questions, and having the comfort of knowing someone who loves him is listening on the other end of the line."
The original telephone is additive: its goal is to take something you value (talking to people you know) and make it easier and more accessible. The phone seeks strictly to add value. Instagram is extractive: a muddled value proposition where occasional joys are paid for with addictive scrolling and a digital slurry of mind-numbing, anxiety-inducing content. The tool isn't aligned with your interests — it's making itself just compelling enough to monetize your time and data. It seeks to extract value from you, not provide it.
Newport's techno-selectionism rests on becoming significantly more critical and choosy about the tools we let into our lives. Filtering by "can this plausibly offer me any benefit?" lets nearly everything pass. Filtering by additive-versus-extractive cuts through: ignore whether something is flashy or potentially cool; ask whose interest it ultimately serves. If it's not yours, why bother? Life's too short to miss time on the phone with grandma.
Highlights
- ▸Additive vs. extractive is the techno-selectionism filter: a rotary landline adds value (call grandma) with no scrolling, comparisons, or dopamine hits; Instagram extracts your time and data while paying you back in occasional joys
- ▸"Can this plausibly offer me any benefit?" is too low a bar — almost everything passes. The right question is whose interest the tool ultimately serves; if it's not yours, why bother?
- ▸Extractive tools advertise convenience but their core mechanism is making themselves just compelling enough to keep you using — they're not aligned with your goals because alignment isn't their business model
Original excerpt
A reader recently sent me a Substack post they thought I might like. “I bought my kids an old-school phone to keep smartphones out of their hands while still letting them chat with friends,” the post’s author, Priscilla Harvey, writes. “But it’s turned into the sweetest, most unexpected surprise: my son’s new daily conversations with his grandmothers.”
As Harvey continues, her son has adopted the habit of stretching out on the couch, talking to his grandmother on a retro rotary-style phone, the long cable stretching across the room. “There’s no scrolling, no distractions, no comparisons, no dopamine hits to chase,” she notes. “Instead he is just listening to stories, asking questions, and…
