One of the nice things is that you don't necessarily have to lose all your momentum.
There's a bit of a learning curve, but you'd find that A2 components are similar to React components, and have similar lifecycle methods. So although some of the specifics about how you do things are different, you can use the same patterns and practices you've been using with React.
That's not to say that you should move to Angular 2. Just that many of the good habits and practices you've developed while using React are portable.
