You shouldn't. Maybe you should learn Hilbert Calculus so you can appreciate it.
It's like asking if what someone wrote a beautiful poem but it's in japanese. Maybe hearing about it motivates me to learn japanese, or maybe it doesn't. But as a non-speaker it makes little impression on me.
Why should I be ecstatic that someone solved a problem using Hilbert Calculus when I can only understand Sequent Calculus? [0]
[0] This is a joke. No 'real' mathematicians do systematic proofs. What gets posted in math journals is the equivalent of architecture diagrams.
