So we know NEW MAGIC will involve a substantial amount of integration with Rails on the server side but it could technically be ported over to other frameworks.

It's interesting because StimulusJS 2.0 and Turbolinks 6 are fully client side based on previous tweets by members of Basecamp. I wonder if NEW MAGIC will be focused on broadcasting real-time updates to the front-end while partial page updates that would normally be server rendered templates could be handled by Turbolinks 6 alone. That would be great news for anyone wanting to create amazing feeling apps with any back-end stack, without going the SPA route.
