The thing is that if you build 2, 3, 100, you'll find yourself doing the same stuff over and over again (and always better than the previous time, so that you'll want to replace all your old code, which is now obsolete), and that's when frameworks are useful.
You know, like Angular 1.
That being said, React seems far less likely to pose this threat, with the caveat that you do have smaller pieces you may have to rewrite as the ecosystem evolves. That being said, in a few years of using React, the only things that have hugely changed are:
1. React Router 2. Use of ES6 classes 3. Better compilers/tools
...That's it. And the latter 2 don't really mean you need to rewrite code, although often you can to take advantage of new stuff. All in all, not at all a raw deal. You get a lot from the work.
