If anything what bothers me is not the lack of innovation in programming languages per se but the relative lack of innovation in program representation. We have high res monitors with incredible graphical capabilities but we still mostly just represent code as flat text files. There've been a few experiments to change the status quo, I remember the Lighttable editor making a bit of a buzz a few years ago, but nothing really changed overall. I wish that a big company like Google, Apple or Microsoft attempted something bold in that space.
