You don’t really have to believe Wittgenstein; any logician will tell you that if your proof is not logically equivalent to 1=1 then it’s not a proof.

Sure, I just personally like his distinction between a “true” statement like “I am typing right now” and a “tautological” statement like “3+5=8”.

In other words, declarative statements relate to objects in the world, but mathematical statements categorize possible declarative statements and do not relate directly to the world.

If you look from far enough, it becomes "Current world ⊨ I am typing right now" which becomes tautological again.
