it should be painfully obvious at this point that bitcoin core is going to do whatever their masters tell them to do, as they have been since "core" got added to the name in 2014 when the cooption started and blockstream dominated the funding for developers. it should also be painfully obvious but most of you reading were not around bitcoin back when the first big bloom of forks hit. blake2b already has an asic, most of them are probably mothballed at the moment. it was for Sia. they switched again and probably a lot of that aluminium got recycled but for sure anyone who had the space and money to store them, they are sitting there waiting for the blake2b fork that everyone is talking about. not to mention the fact that you can rent GPUs by the minute to run any hash function you like at a seriously high hashrate. if you understood how bitcoin (and bitcoin-blake2b's) difficulty adjustment regime works, you will understand that within a few minutes it will be possible to raise the difficulty so high that nobody can mine new blocks for days, maybe weeks. the real solution is changing the difficulty adjustment but almost nobody in the whole world hardly understands how it works, or has enough experience with alternatives, who isn't trying to rob retail, to build a credible one. if only there was someone who knew, and could build one that would actually survive, but not even just survive, but lure bitcoin miners across and crash bitcoin core chain hashrate severely. that would be hilarious.
