Treat the experience more like playing with some sort of odd micro-kernel in a VM, with tools for poking and probing it. Approach it like a software development tool, or a Linux server and it becomes a little less daunting, especially as all the letters are on the screen for quick reference, rather than in a man page.
Still, the beauty of Dwarf Fortress IS that it doesn't care about the UI. It's not for you. It's not for anyone other than it's creators. It's for Zach and Tarn. Yes, it's also for the game's fans, but the brothers have always been building the game THEY wanted to play, and doing exactly what they wanted to do. They're not beholden to a schedule, or some massive revamp required in order to make the game more accessible. They're true to their own desires and souls.
They're artists. This is their art. Yes, it is truly impenetrable, but as with almost all art, taking the time to delve deeper is uniquely and spiritually rewarding. Yes, spiritually.
