Being concerned about AI is like being concerned about tight denim clothing, cheap kevlar vests, cowboy boot spikes, hammer drills, aspirin pills, semi-automatic weapons, and whatnot. People can abuse anything and will abuse everything. The consequences are very likely to be moderately to seriously dramatic, give or take a couple dozen million ruined lives. Happened, happens, will happen happily ever after.
One can hide their head in sand, panicking all along, another can straighten up, master the tool and make themselves invulnerable or almost invulnerable to any damage related to said tool. AI ain't necessarily to ever be mastered but if you have enough theoretical and practical knowledge and can unload it upon people you care for then it's fine and dandy.
I personally am excited for AI generated tomfoolery like those videos trending on social media in which fictitious characters do uncharacteristic things such as Pikachu saving a newborn and nurturing them. 'course people will lose their jobs, 'course AI will be used for propaganda and other misleading. Not unexpected. Nothing you can do but educate yourself and people dear to you.
Global damage... We've seen worse.
