The theory is good, but when my non-technical schoolteacher neighbor wants to use her iPhone to tell me that my package was delivered to her house incorrectly she's going to pop open her iMessage app and look up my phone number, and that's going to come to me as an SMS. There's no chance I'm going to get her to install Signal, she doesn't need it, her circle is almost all blue-bubble iPhone users who don't value anything Signal adds over what iMessages gives them. This doesn't kill SMS/MMS. Not even a little tiny bit. All it does is make MY life more irritating because I have multiple apps that I have to deal with now. The way to kill it is to make something better that people WANT to use, that offers the extra value to make it worth the effort.
