I guess the coutnerpoint is that SMS was invented in, what, the mid 90s? And MMS invented in the mid 00s (?) when things like group chats or sending a video (!) over a phone (at least > 500KB) were inconceivable. We are long overdue for a new, modern, open standard. Apple has in a way invented a pseudo-standard and a) refusing to let others in and b) refusing to also support any other open standard. I think it's reasonable to expect we have a modern standard that supports now-simple things like half decent video transfer, files, groups, locations, etc.
