My recent shower thought was the idea that Moores law hasnt slowed at all, we just went multi-core. Its crazy that the intel folks were so interested in optimizing for single thread CPU design they completely misunderstood where the best effort would be spent - if I had been around back then (speaking as an Elixir dev) I would have been way more interested in having 500 theead CPUs than getting down to nanometer scale dies. Thats what you get when everyone on the team is a bunch of C programmers

Before LLMs, the use of parallelism on your typical laptop was limited to application level parallelism, e.g. one thread for Outlook and one for each tab in Chrome.
