What a difficult question. I think it's confusing for the same reason that there are so many options, we don't know what the future will be. All I can tell you, and what most people will be able tell you is, what tech we are exploring. For me that is React + Flux on top of a c# or groovy backend. Docker is very exciting, but it is not exactly ready since the containers you create in Docker don't actually contain. If I had to reduce my decisions on which new tech to adopt to a primary factor, I'd say it is, does this tech promote a decoupled code base? Applications are getting huge, and whether you are trying to superman a solution as a solo dev, or trying to clearly define a separation of responsibilities across a team, the ability to make modifications to the code with as little knowledge of the application as a whole is what will allow you to develop a large app which is still maintainable. React + Flux - yes c# + entity framework + webapi - yes groovy + gorm - yes docker - yes
