His overall answer is no, WordPress is JavaScript focused. While I think there are a few interesting sessions that Reuben highlighted I feel disappointed to still see WP going down the React route as it is so slow.
As I wrote a few days ago, we should send HTML to users then use some JavaScript to make the interactions a bit nicer. Your whole site should work without JavaScript involved in any fashion.
All this JS crap continues to feel to me like we’re slowly heading back to the Flash days where you had to wait for loading screens.
