So people kind of knew asbestos was harmful wayyy before it mostly stopped being used in 1979 (USA). But, it was still used constantly in many industries and ended up everywhere. What do you think is an example of something we find out is DRASTICALLY harmful 10-50 years from now? My guess would be screen time.


You guess is in the wrong ballpark. It’s unlikely that “screen time” will be found to cause cancer and kill people in painful ways years after they were exposed to it.
I’d bet on PFAS.
There are more ways to harm someone’s life than are dreamt of in your philosophy.
Yeah I didn’t mean it in a completely literal sense that way. I meant more along the lines of what do we view as positive or at least benign. That will actually turn out to be very harmful.
Yeah, I get that. To me the fears about “screen time” seem more akin to past worries about the dangers of technologies like “books” and “bicycles” rather than more direct threats to human health such as asbestos or coal.
