Another potential concern is that it could lead to increased centralization on the network. If only a small group of users are able to afford to include high fees on their transactions, this could lead to an uneven distribution of fees on the network, which could in turn lead to the concentration of power in the hands of a few large miners.
Good example of how GPT is just a statistical predictive model of text; it doesn't have genuine technical understanding.
RBF clearly reduces fees, because you don't have to overbid to avoid the risk of a transaction getting stuck. We were actually kinda lucky that miners agreed to run it. Fortunately, on an individual miner basis, it's clearly better for the individual miner.
