The problem with Meteor is not the front-end. The problem is that data exists (for the most part) in Relational DBs.

This prevents Meteor from being used in any environment that needs to/wants to use a SQL db.

This prevents Meteor from being used in any form, for any application that needs to access existing data in a SQL db.

React does not prevent Meteor being adopted - not having SQL support is a dealbreaker.

If Meteor does not confront and solve this problem nothing else matters.

The only thing MDG should be doing in 2016, is SQL DB support.
