On what timeline though? Vue was looking to be a very strong contender to passing up React, but that has dwindled and it's a solid second alternative but won't end up usurping React. Next.js is one of the biggest hotnesses around web development in general right now, bigger than Svelte, and based on React. While Svelte is nice and shows promise, it's still in the "early Vue" stage and has a long long way to go to make React into a jQuery. Not to mention how ubiquitous jQuery still is.
