One would have to consider the ultimate consequences (including paradoxical ones) of those things too.. Like would it really be catastrophic if social media became unusable for the average user? The 1990s are usually considered the last halycon era... Maybe thats a feature not a bug!

As far as drone swarms, those are definitely terrifying, but then there will be drone swarm countermeasures. Also, is it really much more terrifying than Russia throwing wave after wave of humans at machine gun nests?

I view a lot of the ethics concerns as a bunch of people projecting their fears into a complicated world, and then drastically overextrapolating. This happened with the industrial age, electricity, the nuclear age and so on and so forth.
