"I can't figure out what will be relevant in six months" might have been a legitimate complaint a decade ago, but those days are long gone.
React has been a core part of the front end ecosystem for almost 10 years. Angular is more than 10 years old. Vue is the "new kid" on the block at about six years old.
React is roughly 10x more popular than Vue or Angular according to npm usage, has been far more popular in usage terms for many years, and continues to be growing faster than either Vue or Angular.
Complaining you can't figure out if React or Angular or Vue will be relevant in six months is a bit like complaining you can't figure out if C++ or Java will be relevant in six months. Yes, there is lots of advancement happening in the front end space. Yes, that's a good thing. No, it's not an excuse to act like you're paralyzed to understand the current state.
I'm truly amazed to still encounter "omg React is so new and unproven how can we possibly keep up with stuff like this?" posts. Next up: is no-sql just another fad or will it catch on?
I was around in 2014, when angular 1 was starting to be a big thing.
If you look at reactjs on google trends, react gets its first bump in 2014-15, and then another one around 2017.
VueJs gets a huge jump in 2016-2017.

Java has been around for decades, has had much fewer changes, and is entrenched in a lot of code. In comparison, react has gone through some big changes in a very short amount of time, and most people use it to build SPAs that aren't usually mission critical.
Everyone can set their threshold for when they noticed React at whatever point they choose. Regardless of when any particular individual noticed React, it has undeniably been a big deal for years and can be reasonably expected to remain relevant for years to come. The assertion that "omg front end changes so much how can I know if React will matter in six months" is simply nonsense.
