I read GP's comment differently, that we ended up where we are today (bloated languages, IDEs and runtimes) due to chasing developer productivity at all costs.
Now, developer productivity is becoming less important as developers are factored out entirely.
This was my intended meaning -- the clearest advocacy of this was from DHH about Ruby on Rails, although he's changed his mind about big questions lately and suspect he no longer endorses that set of trade-offs (I don't either, _sort of_ -- I think developer productivity means having simple ways to enable large-scale testing and oversight while minimizing context switching costs, although I think we are all figuring out what that means in practice).
