True, as long as you're using the same versions of the tools... I find that even after a year, if I'm boilerplating something out, even if similar, it's still about a week. The tools change, and APIs between versions break. I had to deal with a react-router change between the last beta and the final 4.0.0 just yesterday (this.context.router.push vs this.context.router.history.push). I tend to mostly lock down my versioning on things to a large extent as a project matures... but even keeping up is more organic.

Starting something new in a year, or 18 months can be dramatically different than the previous start.
