A chain that is attacked is easily going to shift to a different PoW that renders hundreds of millions of dollars of miner hardware obsolete. And the miners know it.

> I would argue that the fork is no longer Bitcoin

You can argue it all you like. Nodes define consensus in bitcoin, not miners.

> I haven't followed the drama super close

Clearly.

You mean like assuming that 80,000+ current bitcoin core reference node users are going to suddenly uninstall their node client software, and install a new unreviewed, untested node client? Because a bunch of suits got together in new york to have a pow-wow? In three months? You mean those adults?

> if they manage to get SegWit enabled

The only reason the nya is accelerating the adoption of segwit before aug 1 is because of these supposed uasf kool-aid drinkers. And isn't it kind of telling that this scalability that has been blocked by bitmain for a year is now suddenly good for everyone? Even though they've been blocking it for a year?

> it is frustrating right now due to scaling.

Take it up with bitmain. They've been blocking scalability for a year now. I'm not that concerned though. I'm happy with just the asicboost bug being fixed and no increased blocksize. Looks like I'm just going to get the blocksize anyway, and I can deal with that. But the hard-fork three months later? You can fork off onto china-coin if you want. I'll just continue using bitcoin.

> Nodes define consensus in bitcoin, not miners.

Again with the kool-aid. Why does the Bitcoin protocol have a POW function and miners? Consensus is defined by the chain with the most work. If you fork and change the POW, you will not have the mining power to secure it. So, it will just be another shitty alt-coin. If you can somehow get the majority of people using Bitcoin to switch over, and somehow get enough mining power to make it secure, then you have something. Thinking that the echo chamber that is r/bitcoin represents the majority of users is laughable though. And thinking that current Bitcoin with the current POW will not continue to exist, have value, have mining power behind it is just silly.

It's strange how many of your belief structure really don't know how bitcoin works. Because if what you said was true, the miners would be able to do what they wanted anyway, wouldn't they? Well? What's stopping them? It's not the 'longest chain' it's the 'longest valid chain'. And what defines validity? The nodes, that's what. It's not like the architecture has changed.

> Satoshi from the Bitcoin white-paper chapter 12 'Conclusion' : The network is robust in its unstructured simplicity. Nodes work all at once with little coordination. They do not need to be identified, since messages are not routed to any particular place and only need to be delivered on a best effort basis. Nodes can leave and rejoin the network at will, accepting the proof-of-work chain as proof of what happened while they were gone. They vote with their CPU power, expressing their acceptance of valid blocks by working on extending them and rejecting invalid blocks by refusing to work on them. Any needed rules and incentives can be enforced with this consensus mechanism.

First, you have to understand what 'consensus' actually means :

> https://en.wikipedia.org/wiki/Consensus_%28computer_science%....

> A fundamental problem in distributed computing and multi-agent systems is to achieve overall system reliability in the presence of a number of faulty processes. This often requires processes to agree on some data value that is needed during computation. Examples of applications of consensus include whether to commit a transaction to a database (or, for example, committing blocks to a blockchain), agreeing on the identity of a leader, state machine replication, and atomic broadcasts. The real world applications include clock synchronization, PageRank, opinion formation, smart power grids, state estimation, control of UAVs, load balancing and others.

Nodes are the agents in a multi-agent system enforcing consensus.

Nodes accept incoming transactions and validate them. Miners don't. Nodes replicate transactions to other nodes. Miners don't. Miners take transactions from nodes, and order them in a block, and perform a hashing function on them (the only thing they do). Miners pass the new block to the node. The node validates the transactions in the block. Miners don't. The node validates the block. Miners don't. The node replicates the block to other nodes. Miners don't.

There is only one function that miners do. They take transactions, put them in a block, and hash them. As soon as a miner produces a block that any node determines does not obey consensus rules, it is rejected. It doesn't even matter if another node has already accepted, because consensus is aligned with all nodes. Any node that replicates non-consensus blocks or transactions is itself rejected.

So nodes accept the transactions, validate the transactions, replicate the transactions, maintain the mempools, validate the blocks, replicate the blocks, serve the blockchain, and store the blockchain. Nodes even define the PoW algorithm that miners have to employ.

Nodes maintain the protocol, not miners. It is thus. It has always been thus.

You should probably question how such a fundamental misunderstanding of how bitcoin works comes about. Is there a source for your opinion?
