In the sense "will you still find new job listings in a decade if you learn it now", then I would say highly likely. In the case its not, the path from React to the Next Big Thing™ will be very publicised and you'll be drowning in blog posts describing the differences.

Yeah, I wonder will we see the Next Big Front-end Thing™ in the following 5 to 10 years. I remember how fundamentally novel and different React felt when it started getting traction.

Now, all its competitors (Vue, Flutter, Svelte, Solid) look very React-like to me. A few minor improvements in some areas but nothing groundbreakingly different.

Elm is different but remained niche and obviously too exotic for mainstream. There's something about the pure-functional approach that doesn't sit well with most people.

Svelte is different from the rest of that list. In Svelte you don't use a virtual DOM to watch for changes, instead you compile the app and hard-code all changes.

That's a difference in implementation. You don't typically think about the virtual DOM when writing react.
