I occasionally compile some statistics on programming language popularity by running a bunch of Google searches to rank programming languages according to the number of results. I wouldn’t read too much into these stats, but they are not without value.
For the last few years (since 2009), I’ve been pitching the idea to my peers that language speed & concurrency/parallel capabilities will become more important as CPU clock speeds plateau and manufacturers add more CPU cores instead of advancing clock rates. My 2+ year old Macbook Pro has 4 cores and 8 hyperthreads.
