Electricity that supplies our house comes from a variety of sources. We choose to pay a supplier who obtains it supply from renewables. Other suppliers still choose coal, nuclear, or other sources. We could switch to a new supplier tomorrow.
And yet they all use the same lines to get their electricity to us. This works due to standards, policies, and various other agreements. And yes there is lots of competition between supplier. And a significant amount of politics and desire to control. However, there is enough governance in place to enable renewables and polluters to use the same delivery mechanism to supply houses.
It makes me wonder, if arch rivals and enemies can do it to supply us with electricity, what is actually holding us back from figuring out data sharing in the humanitarian space?
