The danger in the commercial world is that unscrupulous users of AI will fraudulently mimic famous people and cheat them of their royalties. Or, perhaps even create a "new" human figurine that would usurp real humans, making actors/actresses obsolete.
Further, the greatest danger, IMO, is that these deep fake AI technologies will be used by unscrupulous people to sway all manner of things which we're not allowed to talk about on BITOG. Once the tech is good enough to fool the masses (and it's pretty much there already), then how would one ever know right from wrong, true from false, credible from incredulous regarding any comment or speech given by any public leadership figure?
Truly, we are at the cusp of very dangerous times. But we have shown, as a species, that we are generally incapable of self-control. At times, this can lead to new ventures in life. Other times, we can fall off the cliff into peril. Problem is, until you break through that barrier, you never know what's behind door #3; it might just lead to Armageddon.
