[Perceptes]

It should be noted that Riot is just the first Matrix client to support end-to-end encryption, but there will be more in the future. The thing you want to bet on is the Matrix protocol, not necessarily Riot. (Although both are a safe bet since Riot is developed by the same team that built Matrix.)

I'm not part of the Matrix or Riot teams, but I'm convinced enough that Matrix is a great way forward for modern messaging. I started my own Matrix homeserver (as well as other Matrix libraries, eventually to include a Matrix client) written in Rust. If you're interested in Matrix, Rust, or both, I encourage you to get involved! https://www.ruma.io/
