In the 1990s and the 00s, it was no too uncommon for anti-GMO environmental activist / ecoterrorist groups to firebomb research facilities and to enter farms and fields to destroy planted GMO plants. Earth Liberation Front was only one of such activist groups [1].
We have yet to see even one bombing of an AI research lab. If people really are afraid of AIs, at least they do so more in the abstract and are not employing the tactics of more traditional activist movements.
