LLMs / Generative Models can have a profound societal and economic impact without being intelligent. The obsession with intelligence only make their use haphazard and dangerous.
It is a good thing court of laws have established precedent that organizations deploying LLM chatbots are responsible for their output (Eg, Air Canada LLM chatbot promising a non-existent discount being responsibility of Air Canada)
Also most automation has been happening without LLMs/Generative Models. Things like better vision systems have had an enormous impact with industrial automation and QA.
