So Satoshi Bitcoin will split to Chinese Bitcoin and Blockstream Bitcoin.
If only core developers were capable/motivated/competent to find a solution to increase block size so that people can continue using bitcoin without paying ridiculous fees and insane confirmation time.
Anyways, if there is a split then BTC will not survive as BU needs 70% miner support and if there is 70% support, even less than 50% of those miners can do a 51% attack on BTC, so BTC will need to change their POW as they are planning now, at that point BTC will no longer be BTC but just another altcoin, and a technically inferior coin to many other altcoins.
So why wait for everything to fall apart when the only option is to choose an altcoin and start using it.
Luckily for us bitcoin is still alive and well and it seems the crisis has been averted at least for now but as long as we dont reach an agreement about the future of bitcoin the risk of a fork will still be here with us for a long time.
