Also it is to be noted the following thing: if users are incentivized to delegate according de pools RoS, how long is it going to take before a robot will be available to change automatically delegation according to optimal strategy; switching to higher RoS? Maybe there will even be a fork of Daedalus doing that. And if everyone starts using this robot/algorithm, then it will completely nuliffy the whole delegation system, because we could have calculated the exact same thing without people in the loop, by applying directly this algorithm.
This brings us to why do we give rewards to people who delegate in the first place? And the answer is to secure the network. And how do they do that? By choosing carefully a trustworthy stake-pool! (i.e that will not attack the network) And therefore they should be informed that this is their responsibility, and incentivized to do so, rather that incentivized to delegate randomly to higher RoS pools.
If we let happen this automatic delegation with robots and optimal strategy, then this will probably be the end of Cardano.
