Indeed MetaES may be a way to pave a path to new kind of development. Bret Victor's work, LightTable, Swift Playground and others proved that small improvements are possible. I believe though, that next bigger step requires new fundamentals and metacircular interpretation plus smart IDE and partial evaluation may be very interesting.
I don't know honestly what's going to pop up along the way, but with MetaES we can get smart completion and better debugging experience in popular editors for sure, it just requires more work and care.
