I agree. Also, back end tends to have fewer mega-trends. You usually have the option to stick to your old tools. There are still plenty of C/C++ back end jobs for example. The community keeps branching off.
On the front end, the trends tend to be more extreme; people will not take you seriously unless you give up on whatever tools you use and go straight for React or VueJS... Then when TypeScript comes along, everyone has to switch to that... I couldn't believe it when people started combining JSX with TypeScript... It's essentially a double-transpiled language now... The trends keep adding more complexity and everyone is forced to switch to that regardless.
