> We just watched people spend 3-4 years claiming that 50 Russian internet trolls were responsible for beating a billion dollar presidential campaign.
Fifty Russian internet trolls (likely more), were working to put their finger on the scale, but it's an exaggeration to say definitively that they "were responsible for beating a billion dollar presidential campaign." Maybe they tipped the scale, but maybe they didn't. There's no way anyone will ever answer that question.
It's like hacking. Has a foreign nation hacked the US power grid to cause widespread blackouts? No. Does that mean foreign hacking of US utility companies is not something for Americans to be concerned about? No. Does that mean the US shouldn't harden its power grid against the threat? Also no.
