Bryan Johnson, fresh off a 40- and 70-hour social media fast, says he’s ready to put an AI buffer between him and his social feed.
In a post on X, the 48-year-old entrepreneur and biohacker compared social media to pollution and water toxins.
“Like other toxins, it accumulates,” he wrote. “You can’t unsee or unfeel what you’ve consumed. It settles into mental tissue like heavy metals, producing chronic low-grade inflammation.”
Eliminating social media entirely isn’t realistic, he wrote.
“‘Just put the phone down’ is as practical as telling someone in 19th-century London to stop breathing coal smoke,” he wrote.
Johnson said time away from the apps is the “only remedy,” but he also suggested that AI agents could serve as an antidote to social media.
“An AI layer between you and the feed. Filtering rage, removing vanity metrics and translating sensationalism into calm, factual language. Preserving signal and eliminating noise,” he wrote.
“I never want to see the raw feed. I want an AI agent to read it for me, strip the engagement metrics that hijack my judgment, filter the rage, and return only what I actually came for,” he added.
In a world where AI agents are already proving to be expert hackers, agreeable coworkers, and custom-built board members — as well as potential security risks — Johnson’s push for an AI layer between himself and his feed doesn’t seem all that far off.
Johnson has made it his life’s focus to try to reverse his biological age to avoid death. He spends around $2 million a year to do so, focusing on extreme treatments such as plasma therapy alongside his strict diet and exercise routine.
His wish for an AI social media buffer also ties into his quest for a longer life, he says: “I want social media to become a longevity intervention, not a longevity threat.”
