May I be blunt? I estimate that 70% of all OpenAI and 70% of all "insiders" are full of crap.
What people are calling nowadays "AI" is not a magic solution for everything. It is not an existential threat either. The main risks that I see associated with it are:
Assumptive people taking LLM output for granted, to disastrous outcomes. Think on "yes, you can safely mix bleach and ammonia" tier (note: made up example).
Supply and demand. Generative models have awful output, but sometimes "awful" = "good enough".
Heavy increase in energy and resources consumption.
None of those issues was created by machine "learning", it's just that it synergises with them.
