I think it's still pretty decent given the circumstances. DNS is pretty well designed otherwise. Email exists thankfully. Internet packet routing itself isn't too bad. The problem is there is really nothing new in terms of protocols being adopted that are similar to email and DNS. Email feels clunkier by the day while messaging apps with proprietary protocols controlled by a single company gain more and more functionality and use. Standardized messaging protocols and similar things are rarely picked up by any company. And some companies pretend like they're creating some open thing like Signal, but it's just another reinvention of the wheel controlled by a closed group. And there's always people pushing magical "decentralized" stuff, but it's never really a solution to anything.

Email (SMTP and IMAP protocols) is the model that should be followed but it isn't "sexy" enough and there's no profit incentive for anyone to make anything standardized. Protocols like Session Initiation Protocol exist for messaging and VoIP/Video but they're kinda clunky and people don't want to do the work of implementing them.
