Early AIs performed automated tasks like assembly line operations. Though most people don’t count them as even proper AIs. More like dedicated programs with a single job. They gained advanced decision trees over the years and decades that followed to make them far more capable. Aircraft autopilots had similar growth rates in their own times, advancing from simple engine and flap locks to automated systems that could launch, fly, and land at their final destinations while the human pilots did nothing but watch and oversee. These systems automated dangerous or boring tasks and allowed humanity to sit back and spend more time reflecting on the nature of life itself. Or trolling the social networks for amusement. Whichever they preferred.
