We could use friendly language for a long time
Does this mean programmers who like to be happy (especially Ruby programmers) need to count their days? Nope. I was reading this article https://thestack.com/world/2016/10/07/law-defying-transistor-smashes-industry-limit-measures-just-1nm/ where a group of researchers have created a transistor just the size of 1 nano meter. Though its not based on silicon, but based on carbon nanotubes which means we need new fabrication process, it does gives hope to us that computers will turn out to have more processing per watt and per unit volume. So we can write software that would make computers understand us more better than the other way around.
I still feel Ruby has a great future. Ruby is evolving internally, that is its becoming faster, at the same time hardware is getting faster too. Human friendly languages have a long long way to go, and I feel their wings will expand to many more domains.
