The whole "generating" rewards is just the most high level view of them all. If anything it might be interesting to keep a permanent track record of some conversation as part of a digital history.
There is an incentive structure in place and the ecosystem has been shrinking since the steam from the STEEM fork cooled down. Hence, the incentive structure is a failure. But that will never be accepted by the biggest whales, therefore the outcome is already predestined. Imagine the market turn around in 2025, $Hive drops another 95%, some people start to gobble up even more and other decide to fork away due to centralization. Hahaha.
Maybe, maybe not. Certain is, all the value of the Hive Blockchain can be view as a projection of energy through all wallets. I believe the Market Cap will at some point drop far below the value of the wallets and strong winds of change will arise. At that point, it is adapt or die for this fork.
