So C, C++, and Rust programmers will be in demand, and other languages will shrink?
Does this also relate to rising DRAM costs, which will make memory-efficient code more usable as we head into an unseen future?
Until current computers cycle out, people will largely keep their 1-3 year old machine with sane amounts of memory. If we start seeing large numbers of machines in the wild with 4GB of memory, then maybe software will adapt. But that won't be for several years yet.
Projecting into the future, hardware expenses have always been dwarfed by salaries. I don't expect that will change enough for it to be noticeable.
