Jason is referring to the long‑dormant parody X (Twitter) handle @Fakechamath and says, right after Sheryl Sandberg reveals Dave Goldberg ran it: “My guess is that Twitter handle is about to get popular again. It’s going to get pretty popular.”(podscripts.co)

The episode’s show notes confirm that the handle in question is indeed twitter.com/fakechamath.(podcasts.apple.com)

Third‑party X viewers such as TwStalker show @Fakechamath having roughly 3,000 followers and 60 following, with multiple independent profile snapshots in 2025 all reporting about the same follower count.(ww.twstalker.com) However, these tools only expose the current count at the time they crawl the profile; they do not provide a time series or a pre‑May‑2024 snapshot. X’s own interface is behind a login/JS wall and likewise doesn’t expose historical follower numbers.

Because there is no accessible data on how many followers or what level of engagement @Fakechamath had before the May 3, 2024 episode, we cannot rigorously determine whether it became “significantly more popular” afterward. The current modest size (~3K followers) also doesn’t clearly prove or disprove a large relative increase from its prior baseline.

With sufficient time elapsed but no reliable before‑and‑after metrics for popularity, the outcome of this prediction cannot be determined from available evidence, so it is best classified as ambiguous.
