Technically we could build something like LoRa on the amateur bands. It's a pretty basic protocol with up/down chirps.
With the kind of power we can use compared to the ISM bands this kind of robust protocol would have a huge range.

As someone who's had the most ham radio success with FT8, I do find myself asking "what if there is an emergency"? I probably won't have power for my computer, and WSJT-X is pretty cumbersome to use while mobile. So we should probably be looking into other technologies, but the old standby CW seems good enough, so nobody is really looking.
