I agree, I know eventually the datalist won't lag on scroll with even just 100 items in their datalist control, and that they'll name their dropdown picker to something other than "-webkit-calendar-picker-indicator" since it's misleading https://jsfiddle.net/klesun/mfgteptf/ If I sound passive it's because I assumed a native control/component would be performant and switched out a lot of controls for it only to have to revert back to a custom solution. But ultimately they will be fixed and it'll happen to us transparently which is nice.

Not exactly a tribe, but there is the case of the Lykovs: https://www.smithsonianmag.com/history/for-40-years-this-rus...

They just figured that the other humans were probably up to some fancy shenanigans again, instead being impressed by things like cellophane (granted, they had the benefit of knowing of the existence of the outside world).

I think it might be similar for many isolated tribes. By now they have probably seen enough signs to deduce that the things they're seeing are created by fellow humans, since satellites and planes have been a thing for a few generations now. Especially with satellites having predictable orbits.
