Good point.

It’s the 4th generation memory wipe effect. Once the current grandparents have no direct experience of the thing, forget about the thing.

Unless of course you’re forced to, like for your job. My place would have little to zero sympathy for my personal reasons not to travel unless it’s on a govt advisory not to.

At least for foreigners travelling into the US, you’re willingly giving the US govt most of this information up front anyway via the APIS. And paying for the privilege!
