Yes/no is a false dichotomy.
"Getting better" how? Presumably this means "as a guitarist," but even so limited, think about all the different aspects of "being a guitarist" or "playing guitar" in which one might "get better" [especially if one is a guitarist in performing situation(s)]. Phrasing? Creativity? Technique? Speed? Adaptability to new situations? Ability to play in different genres? Keeping cool under adverse conditions? Multitasking (singing/playing, cueing others while playing, connecting w/audience while playing)? Knowing your limitations and not making a fool of yourself by trying to play too far above your head (not an issue if a bedroom guitarist or just jamming with friends, but for a performing guitarist, can be important)?
I'm probably not getting better in most of those more technical things in the first half of the above list, but making some strides in the more general/"performance/stagecraft" aspects of the above list, which is where my strengths lie anyhow. I'm also making some improvements as a singer (not to say that I'm a good singer, just getting better at using what I've got) and songwriter.
