With regards to the recent dos + inflation bug, and seeing that most nodes on the network have still not upgraded with the patch (lukedashjr's chart here: https://luke.dashjr.org/programs/bitcoin/files/charts/security.html), I think the least understood aspect of Bitcoin to me is this idea of economic majority. Can you someone elaborate on the economic majority? Suppose in a scenario, I have a node running following the rules of Bitcoin Core v0.17.0 and if I die, but I still want those rules to be enforced, can I do that? Do ancestor nodes have any consensus role to play or only the ones being used today ("economic" nodes, i.e. exchanges, miners, merchants) matter?
