Back in the 80s, when I started programming, I learned XLISP and CLISP. But then some people said, that these languages are somehow outdated. And I naturally got a little unsure because I was very young. So it is very funny for me to see Clojure used in production in web and micro services for a large german car manufacturer in 2017.
Learning: There are constants in computer science. LISP-like languages will (probably) always exist in the future.
The conference itself was wonderful: Interesting talks, nice people, nice location in Prenzlauer Berg
