Reading matrix’s blog posts they seem keenly aware of the issues surrounding it being a discord replacement and the complications with self hosting. It seems they are responding to the community but are also pretty stretched thin for having the money to develop it quicker and turn things more polished and user friendly. I’m hoping the influx of new users will also result in an influx of donors and some rapid progress.

That being said, if not matrix, I expect someone will take up the mantle and in the not too distant future there will be fairly literal drop in replacements that are oss.
