We learned this lesson the hard way. A few years back, for a start-up, we picked angular 2.0 as our choice for frontend stack, when it is released. Though it was fun to develop it, We faced a lot of unknowns and issues to finally ship it.

Too many changes for each version, The bundle size was too big. Angular SPAs were not great for SEOs etc. We ended up missing the shipping deadline by a couple of months.

When you really want/have to `ship it`, pick any technology you and your team have delivered something before.

When you have time to explore, pick any new shiny technology, and concentrate on learnings.
