I think the author is suggesting that Remix was the inspiration for the renaissance, not that it's necessarily the most popular method for doing so.

I'd be curious to see the stats on how often Next.js users lean into the server component model that makes the frontend fast. My anecdotal experience is that it's an afterthought for many. By comparison, Astro (as mentioned by the author) makes you think about this stuff upfront via opt-in rather than opt-out. It's a wonderful framework.
