I think most of us agree that writing code can be expressive. But I don't think that alone qualifies you code as art.
I have written code myself that I deem beautiful and expressive. But I'm also a musician, and making music (and listening to it deeply) has given me such intense, mystic experiences, that they dwarf anything I've ever experienced writing code. It's also much harder to make good music because it requires a kind of courage and psychological constitution that is simply not required for writing code.
I respectfully disagree, I think code has always been more of an art than a science. It's an odd one, I'll grant you, as you need to do a lot of work to really appreciate it.
