I don't think it's overstating it at all. If anything, I would argue that code is more expressive than literature or music because it's more general. Consider the space of all possible video games, demos/intros, generative paintings, generative music, etc. which wouldn't be possible without code.

I think you're confusing the common use of a medium with expressiveness. Many uses of ordinary language also aren't that interesting, but we need to consider the full space of possibilities.

In the 1980s, you often had programmers create the art and music for games, but for the last three decades at least there have been dedicated artists and composers who often have no coding skill at all.
