The distribution is asymmetric for obvious reasons. The probability for 2014 is pretty close to zero. This means that there is a 50% probability that a serious code project will start after 2020.
This is inconsistent with 2017 being a median estimate.
The first estimate: 50% probability between 2015 and 2020.
The second estimate: 50% probability between 2020 and 2035. (again, taking into account all the conditioning factors).
Um.

Unless he thinks it’s very unlikely the project will start between 2017 and 2020 for some reason.
Good point. I’ll have to re-think that estimate and improve it.
