I think we need to be careful with trusting even our own anecdotal evidence because it's simply riddled with biases and bugs. 30+ years of experience is certainly impressive but I'd say you probably never worked in a senior team on a larger Clojure codebase for example which would give you quite the opposite impression. You should read the anecdotal evidence in that community, it's very different.
