- 08:4708:47, 2 April 2024 diff hist −2,018 Combinatory logic rv and put a disclaimer on what remains. (1) This is a large chunk of unsourced original research (WP:V, WP:OR). That alone makes it a no-go. (2) Despite the deceptive claims, this argument does not in any way prove the undecidability of combinatorial logic, but a much, much weaker, essential trivial statement that has nothing to do with actual undecidability.

This argument does not in any way prove the undecidability of the problem. Plenty of obviously decidable problems (e.g., “does a term start with K?”) are not definable in this way by a “predicate” either. Tag: Reverted
