The Dangers of Truth and Utility

Truth and utility being co-constitutive, I suppose, or like, if there's a truth that's not, that doesn't have utility, what is that? Because I think Deluzz is sort of on that same track or train of thought. And so it's about practical, it's kind of, I'm going to say this, but I'm not necessarily going to use Kant's definition, but like a practical reason.
