So acquiring immunity to a lower-risk version of the service before it's ramped up? e.g. jumping on FB now as a new user is vastly different from doing so in 2014 - so while you might go through the same noob-patterms, you're doing so with a lower-octane version of the thing. Like the risk of AI psychosis has probably gone up for new users, like the risk of someone getting too high since we started optimizing weed for maximum THC. ?

There's also a massive selection bias when the cohort is early adopters.

Another thing about early users is they are also longer-term users (assuming they are still on the platform) and have seen the platform evolve, which gives them a richer understanding of how everything fits together and what role certain features are meant to serve.
