As always with AI we need to ask: 1. Is AI good at this? 2. Should we use AI for this? People are often surprised not only by how hard it is to answer (1) but also by how (2) is a completely separate question than (1)!

I am hiring! There are probably about ~12 people in the world who meet exactly what I'm looking for, so we're open to considering teaching a 13th person to do what I do provided they already have a strong background in Bayesian statistics (non-negotiable) docs.google.com/document/d/1...

Reproducibility packages are a communication tool more than anything else. I wrote a bit about this, in a seasonally appropriate post, once upon a time statmodeling.stat.columbia.edu/2019/11/13/w...
