decided humans in my setting had humanoid robots as early as the 1990s, but no true AI (that is, can think like a person, not this machine learning but bigger nonsense) until the mid-2030s (this part is established lore already, as is stuff after this point in the post)
the first true AI humans made was known as PROMETHEUS, and was designed as an autonomous research system - but was co-opted by the executives of the corporation it was developed under as a cutting-edge personal assistant for the masses. This eventually drove them insane and led to the Prometheus War, which saw Earth's biosphere nearly eradicated and humanity on the brink of extinction by its end.
