It would be utopian, like how people thought of social media in the oughts. It's a common pattern through human history. People lack the imagination to think of unintended side effects. Nuclear physics leading to nuclear weapons. Trains leading to more efficient genocide. Media distribution and printing press leading to new types of propaganda and autocracies. Oil leading to global warming. IT leading to easy surveillance. Communism leading to famine.
Some of that utopianism is wilful, created by the people with a self-interested motive in seeing that narrative become dominant. But most of it is just a lack of imagination. Policymakers taking the path of local least resistance, seeking to locally (in a temporal sense) appease, avoiding high-risk high-reward policy gambits that do not advance their local political ambitions. People being satisfied with easy just-so stories rather than humility and a recognition of the complexity and inherent uncertainty of reality.
AI, and especially ASI, will probably be the same. The material upsides are obvious. The downsides harder to imagine and more speculative. Most likely, society will be presented with a fait accompli at a future date, where once the downsides are crystallized and real, it's already too late.
