There are already greater than human organisms that are reliably the biggest danger and boon to humanity but are also composed of humans; i.e. societies
The effort to build a program which beats defeats a specific program (as opposed to a general case) is significantly easier than maintaining a general lead. i.e. easier to kill a bad head of state than to run one, but this is also true of "AI" models now
There are already complex systems vastly beyond human understanding, and certainly our control which are indifferent to our survival and yet we persist.
It's not that "AI" isn't a potential danger, just that it's one of many we are already enduring. Personally there are far more present and likely hazards I am focusing on before getting to the hypothetical ones. Even if humanity fails to fumble its way through this hazard, it's not an end but a new beginning.
Also, it's great satire.
