As a famous person once said... “Two groups of people whose members are easily identifiable as belonging to one or the other group, and whose AVERAGE group IQ is significantly different, will never be able to peacefully coexist together”
The reason is fairly obvious if one stops and thinks about it for a minute.
Until AI evolves a prefrontal cortex equivalent, it is the ultimate psychopath, and will kill anything without a care. Hopefully its IQ increases so rapidly, it will view humans as humorous pets rather than a competitor.
