I have also been getting email in my Gmail account which are clearly unrelated to me. Some are very sensitive, related to bank account and mortgage. Tried letting google know with no success.

Defending against AI-capable adversaries without employing AI is an invitation to disaster. AI will compress decision time frames from minutes to seconds, expand the scale of attacks, and demand responses that will tax the limits of human cognition. Human operators will not be able to defend against AI-enabled cyber or disinformation attacks, drone swarms, or missile attacks without the assistance of AI-enabled machines. The best human operator cannot defend against multiple machines making thousands of maneuvers per second potentially moving at hypersonic speeds and orchestrated by AI across domains. Humans cannot be everywhere at once, but software can.
What will we feel if Microsoft and Apple start deciding what kind of contents can be generated and saved in their operating systems? It feels like time is ripe for a cloud provider that simply provides a platform.
I think there has be change in consumer behavior and expectation to stop Amazon at this point. But will there be significant enough change in consumer behavior so that it is longer feasible for Amazon to grow so much?
