Moores Law does not help it get more secure.
How about we work on things that mater in this post-Snowden world, like increasing security -- and let Moore do the performance improvements! Seems a more reasonable and efficient approach, no? Adding more attackable surface area to the Kernel is not a good idea at all. It is an NSA wet dream.
How I wish. Sure, for proprietary and commercial consumer-facing apps, it might be the case. There's a ton of proprietary/commercial development tools and infrastructure (hyper-optimized JVMs, k/kdb...) that are inverses of Wirth. FOSS has its opuses as well, but it's just as full of crap.
Amdahl's law only really makes sense in parallel computing.
Sure, but that doesn't mean one can just magic away blatant bottlenecks, and even if some speedup is possible, it does not retroactively make these decisions correct.
Contemporary computing is parallel computing. Even phones have multiple cores.
