Lisp people (like Paul Graham) say that a lot, but they also admit that there’s a pretty steep learning curve before you get to that point - at least, I’ve never heard anybody say that Lisp is both easy to use and easy learn. I actually do believe them. I used to hear the same thing about vi: it’s quick and powerful, once you get over the learning hump. I actually did take the time to get over the hump and found that I _was_ faster and more productive with it, but it took some time to get there. The time spent was worth it, but it was slow going getting there. I’ve dabbled enough in Lisp and functional programming in general on my own to believe that there’s something very powerful hiding in there… but there’s work to be done and unlike my choice of text editor which only impacts me, I have to work in a language that everybody agrees on, and so far, that’s never been Lisp.
