LMFAO every example of "modern" looks like a course in how not to design an API, etc. The jQuery examples are so clean and expressive. Imagine landing on a page like that and thinking, "hey, that 'modern' option looks good." You'll end up with 28KB (jQuery gzipped size) of just extra syntax before you're done with your app, not to mention the additional 160 hours of work.

You'll likely be adding 6-700KB of React and its ilk anyway (I see it in every project now).
