I know of at least 3 banks that use python2 inside their trading platforms (the big two use python as the built in scripting languiage) -- which would be a multi-year multi-10s-millions project to migrate to 3.. We won't be saying goodbye for a while... For standalone stuff, yeah, it's not so bad. Upgrading between node releases has been more painful to me than python 2->3..

Wow! What are the problems you encountered upgrading Node releases? I noticed how they removed tail-call optimization, which broke Lamdu.

  Pinned dependency X stops working in Node X+1. Upgrading dependency X to work on Node X+1 breaks code using dependency X. Sorting out the mess stops development and leads to cascading breakage. So just say "fuck it" and wrap the project up on a Docker container running Node X. Now work can continue. Luckily the project is internal so missing security fixes is less of a problem than something customer facing.

>Upgrading between node releases has been painful to me This is surprising to me. What kind of deps do you have that are changing? From my view starting around Node 4, only Buffer really went thru big API refactors, and otherwise going LTS -> next LTS is seamless
