It's starting to look like segwit2x (BT2/B2X) will be nothing more than another BTC alt whose blockchain will die a slow agonizing death like bitcoin cash. Regardless of my own opinion on segwit2x, it appears to be an attack on bitcoin to me. It's is a hard-fork with no consensus, extremely dangerous. So dangerous that coinbase will halt its BTC operations right after the fork because nobody knows which chain will be viable. My totally semi-educated guess is that at first both chains survive and that B2X continues to get treated like an alt. It would take consensus to actually replace BTC with B2X, a lot of people believe that means just "miner consensus" but they'll find out quickly that isn't going to be enough.
The Litecoin team appears to have figured this all out. Litecoin doesn't need a 2X hard fork, and off-chain scaling solutions are already being built. A lot of people cracked jokes at Litecoin for implementing segwit while it's blocks were mostly empty, let's see how much they're laughing in a few weeks. They probably didn't learn about the seven P's.
