Most of the languages we code in are almost 20 years old, and the techniques and conventions for coding in them even older. Core architectures are based on design conventions that existed before most of us started programming. The fast innovation mostly happens around the edges. We have more cores and memory caches and our address spaces have gotten larger but the most popular computer design, if I am not mistaken, is still the register-based machine. In that case despite advances in hardware, C and it's derivatives have scaled rather well to the problems at hand. Given a sufficient proficiency for abstraction an evaluator should be capable of emulating any machine required to run a given process. Which is what has allowed Lisp based languages to scale and continue to be relevant over the last 50 years. Some developers talk about "age," like it's a bad thing.
