I was with you until here
Thanks to the re-rendering model, React needs to tie the state to the component structure
This means that in any other framework I can create the most complex app in the world in a single component and have a performance superior to the equivalent most optimized React code
You agreed with @jovidecroock.com's take, so I suppose you also disagree with yourself here. I get the overall point, but this one taken literally is wrong.
React code is slow for reasons much different to other frameworks. It does not follow that experiences will be the same in other frameworks.
