Humans are inherently bad at reasoning about rare events. In 2019, many people implicitly reasoned that "since there hasn't been a pandemic in the past 3 years, there won't be one in 2020". Bill Gates was one of the few voices arguing that the world was quite vulnerable to a pandemic. Now he's arguing that the world is quite vulnerable to AI.

The necessary IQ for destroying the world is dropping. Op does not say it's low enough today, but that will probably come sometime. Denying the possible harm these tools are capable of doesn't help.
