Until recently, always-available, extremely-low-bandwidth, text-only communication was interesting, but not that interesting. You could use it in emergency situations or to talk to friends, depending on how low-bandwidth we're talking about, but that's about it. You couldn't use it for internet browsing or to look up information you might need on the go, you basically needed to text a friend to do it for you.
If the other side of that communication has access to an LLM with internet browsing capabilities, the situation changes dramatically. If there's something you need to know on the go, you can just ask Chat GPT to do the searching for you and respond like it was writing a Telegram (in the most concise way possible).
