The headline is a perfect example of a tense-critical deepity: it's trivially true because of the "is" and would be trivially false if it instead used "will be"

The headline is a perfect example of a tense-critical deepity: it's trivially true because of the "is" and would be trivially false if it instead used "will be". Best practice would be for headlines like this to always be explicit by adding "right now", e.g. "The greatest risk of AI right now is from the people who control it, not the tech itself." Once AI commonly acts on its own, things change.
