That's the truth. In the case of October 7 (and 9/11 for that matter) lots of useful info was coming in, and regardless of the source, it was actively ignored. Human error at it's best. AI analysis is just another tool but ultimately we need competent or empowered people involved in the chain.
Yeah the best way to fix errors is to ... just ignore them.
I think any sophisticated system that requires a bureaucratic staff to operate is doomed to fail.
