A couple years ago people were recommending Vue as an effective alternative to React's complexity.

Then Vue itself became complex.

Now people recommend Svelte as an effective alternative to Vue's complexity.

Will Svelte remain simple?

It's not hard to see this constant cycle of "simplicity -> people need more -> complexity -> let's jump ship" if you're a web developer with more than a few winters. Every time there's a new simple library around the corner that makes reality so much easier to deal with, but it's mostly just hype speak and this simplicity never lasts for long.
