No slight intended obviously to people who do write actual client code. That was probably insufficiently specific, let me rephrase: I am referring to the trend that much of the industry is built on web2.0 technology using bitcoin via a library in a web scripting language, often with consensus bugs, and even outsourcing and not even running their own full node, so that the service itself offered to their users isn't even SPV secure to the operator. As well as being heavily based on a third-party custody model that is the root cause of the repeated wallet breaches. Some of these companies have a noted tendency not to upgrade or fix code. So I mean this not to call out specific companies, but in the sense that if we're technologists we should be trying to move the technology forward, not just changing parameters which run into an O(n^2) scaling wall or break decentralisation security. And we shouldnt take the above state of affairs as an immutable reality. It can not persist for bitcoin to reach maturity on scale nor security. > I still think you guys don't recognise what you are actually asking for here > - scrapping virtually the entire existing investment in software, wallets > and tools. As I said I dont think we can expect Bitcoin to scale with no further algorithmic improvements. Algorithmic improvements take code. There is reasonable scope to build in an incrementally deployable way, there's plenty of time for people to code, test and opt-in to things, the sky is not falling. Companies do care about scaling, and can invest in the integration and coding implied to improve their products scalability, they have an economic incentive to do it and there is no scalable and safe way todo it without this work. > Computational complexity for the entire network is O(nm) where > n=transactions and m=fully validating nodes.

I am referring to global bandwidth O(n^2) with n=users, or O(n) per user bandwidth cost to the system, while O(nm) is accurate nodes is an internal system concept. Anyway suffice to say the network does not scale O(1) in per user cost. > "Exposing the companies to back-pressure" sounds quite nice and gentle.

A hard-fork takes a long period of time to deploy due to the non-upgrade risk, people are working on things in the mean-time. There can be a case for some increase to create some breathing room to work on scaling and decentralising tech, I just mean to say that if we do it in isolation, we're not focussing on the big picture.
