Peter Todd is the creator of RBF and the biggest advocate for making every transaction enable the feature by default. He wrote this article to explain his point of view: https://petertodd.org/2023/why-you-should-run-mempoolfullrbf Sergej Korliar is the CEO of Bitrefill and an advocate for 0-confirmation transactions, as long as the receiver is willing to take the risk. He considers that full RBF effectively destroys the 0-confirmation use case, potentially slows down Bitcoin adoption and makes users migrate towards altcoins for commerce. This episode is a debate between the two perspectives. It also marks the first time in a while when the two of them sat down to talk and this fact is reflected on how tense the interaction became towards the end.
