> and was actually trying to make stuff better for users
Now, if we're talking about making communication between users better than yeah you need to go beyond email. E2E, open protocol, something like jmap (imap sucks), focus on privacy and interoperability, yada yada, so many better stuff to "fix" before trying to amplify my inbox and adding more rendering issues between platforms. Do you see a trend? You're now treading a thin line between chat apps, social networks, Android instant apps and glorified iframes. And introducing a whole new set of problems at the same time, not to mention the monumental effort required for something like this to keep backward compatibility (just so you can still call it email and use the superset). And getting the implementation right the very first time.
I too want the worst problems of using email to be solved but since nobody wants to adopt open protocols and work with each other (or eee the whole thing a year later), like history showed us time and time again, it won't happen. So again, let's at least no lose what we have now.
