For context before that I had ~15 years of experience coding the traditional way.
I think the crucial difference is that I do actually see evidence (ie the codebase) posted sometimes for the former, the latter could well be entirely mythos -- a 24 day old account evangelizing for the legion of agents story does kind of fit the theme.
Let me guess this has something to do with AI?
In what way? Lisp (Common Lisp) is the most stable and unchanging language out there. If you learned it anytime after the late 80s, you still know it, and will know it until the end of time. Meanwhile, here, we hear that "a year ago" is so much time that everything changed (for the better, of course).
Or is it about needing some serious time investment to get comfortable with Lisp? Even then, once you do spend enough time that s-exprs stop being a problem, that's it; there's nothing else to be getting comfortable with, and certainly, you won't need to relearn any of that a year into the future.
I don't think AI coding and Lisp are comparable, even considering just the tone of messages on the topic (as far as I can see, "smug lisp weenies" are a thing of the ancient past).

Also liszper: oh, you tried the current approach and don’t agree with me? Well you just don’t know what you are doing.
