I think you have to think in Satoshi. There are 100 million in a bitcoin. The technical stuff re. scaling and fees can be fixed (theoretically). Satoshi can be further subdivided if necessary. The issue is governance - how do you get upgrades done on the bitcoin network given all the ideology and division around SegWit2x. If these things don't get fixed then bitcoin is Gold 2.0 for international trade (assuming volatility dies down) and some other crypto becomes the "digital cash" of the bitcoin whitepaper vision.
