I've been enjoying Swift a lot, so it doesn't surprise me how quickly it's overtaking OBJC in popularity. What did surprise me about this index is that Ladder Logic is still a thing, let alone ranking in the top-50 of programming languages. I remember "coding" in that stuff back in the 80s working with industrial electricians. Good times.
