I think they mainly employ a JavaScript perspective where a frameworks lifetime is measured in minutes.

Sure many classical backend frameworks use a central database technology which limits their scalability, but the mature frameworks with sufficient backing behind them still do the job and save a ton of time. With those you will end up with a maintainable application on the long term. Think of django, heck even JavaEE if done right.

Most of you are not Google ;)

I've started using React.js in 2014 and I'm still using it today. That's probably quite a lot of minutes TBH.

Month ago I've started another project - again React + Redux. I don't think React.js will disappear from the scene anytime soon.
