we've got both Moore's law for compute and Nielsen's Law for bandwidth going for us.
for users with unlimited 5G+ or wired access and fair use unmetered plans, I'm not sure it needs to be solved for them
for users on metered plans and 3G/4G mobile networks, perhaps. this would impact usage in developing nations the most
i think it's possibly solvable with relay focused, interoperable NIPs that clients can adopt to make traffic more efficient
