I have trouble imagining a comeback because Forth&#x27;s unique value is in staking out the tiny-and-simple end of the efficiency frontier. But Lisp is almost as simple if you can spare more resources, while if you&#x27;re OK with complexity there are compilers that optimize better.<p>It&#x27;d be nice to be wrong, since I&#x27;d love to work in a system where every bit is handcrafted and known to me. I didn&#x27;t quite get there back in the 80s in my summer job at FORTH, Inc. but it did teach me a bunch and I enjoyed scrounging out a few bytes here and there.
