He was a comp-architecture guy counting on the device/physics folks to deliver. They didn't, while Jim put his reputation on the line. He probably resigned in disappointment and/or protest.
- Moore's law is dead at the physics level.
- Exponential tech progress doesn't stop but it won't be in the form of Si FETs, at least not in the foreseeable future.
- There is plenty of opportunity at the higher layers of abstraction though.
- Fortunately the AGI problem has escaped Moore's law (AGI can happen with existing node technology). And in my opinion that's all that matters for the next 10 years.
