Academia. I'm going to pick on something specific:

* Reproducibility -- running code months or years later, on another machine.

Current tools, like VMs tend to be too heavy-weight. Docker is too hard to set up.

The main problem with these various tools is that exploration is slow -- Often I'll take an experiment, tweak it a few dozen times, then finally get the code for a paper. At that point I don't want to package it up, I want to be able to "freeze" where my last execution.
