SMS is important. It's universal, and it can be used as a way to communicate with anyone. I have friends that I chat with exclusively over SMS. They use Facebook Messenger, and I won't use Facebook anymore. They could join me on Signal or something, but I'm not going to ask them to download a whole app just to chat with me.

It's the one messaging platform that's not in a silo, and that's just as important (maybe more so?) than 100% reliability.
