I wonder what general purpose languages (as the mentioned Jai is meant for games primarily) will be the best fit for modern architectures, besides obvious things like doing it in C and just doing everything manually to fit the machine nicely.
And rather surprisingly, it always has, even when memory latency was 1 cycle and there was no prefetch (for which you have to go back to the late 70s). The first APL implementation is from 1962 or so, first Fortran is 1955 or so.
R and Numpy use it to deliver their speed while still providing high level semantics.
I'm looking forward to zig. The author is taking a lot of care and effort to make sure the content works on legacy systems as well as modern systems, so I think the level of flexibility that entails will also mean the flexibility to adapt to the future.
Also, IIRC zig has an AOS to SOA transformation in its stdlib? In any case, they have been refactoring the language parser to use SOA to great effect:
