Jim Keller gave a talk at Berkeley titled "Moore's Law is not dead" (2019) where he summarized a bunch of up and coming technologies that will enable the continued scaling of transistor density - https://www.youtube.com/watch?v=oIG9ztQw2Gc https://www.youtube.com/watch?v=oIG9ztQw2Gc
- hinkley 3y agoHow many of those are invalidated by Specter? We’ve been building chips that are literally impossibly fast for half of the last decade at least.
- GuB-42 3y agoSpectre is just about timing attacks on branch prediction. It has nothing to do with transistor density, and it can be remediated with a reasonable impact on performance, that is if remediation is necessary. These vulnerabilities are also hard to exploit in real life and not always relevant. Rowhammer has to do with RAM density, but again, hard to exploit and there are mitigations.
- renewiltord 3y agoNot that important depending on use-case. Lots of people have been running for years with `mitigations=off`. If someone could steal their crypto, they would have. https://news.ycombinator.com/item?id=32077583 https://news.ycombinator.com/item?id=32077583 I run with `mitigations=off` in offline cluster.
- xw390111 3y agoMoore's Law has been entirely coopted by the media and, as such, lost all meaning and predictive power, which is what made it famous in the first place. Once upon a time it was a useful tool to plan programs with. So outside of popular culture, it is dead...
