Not sure what the context was, but that's correct. Pointless, like any philosophical argument, but in and of itself, true. The only true thing you really can know on this side of the separation from God is that you know nothing.

But since you ”you know nothing”, why should anybody listen to you? It is just silly.🤷
Exactly. Now the next step - if you understand that you know nothing, and can never know anything, then what's your relationship with Truth? And how do you live in Truth? Pride ; or humility? Slay your ego. Your ego is as pointless as anyone taking you seriously.
