What if it starts out as a minority chain, and takes over the majority chain after 6 months ?
actually the even funnier scenario is this in my opinion:
BIP148 breaks away as a minority chain and start being proud of having SegWit and be good but the majority chain activates SegWit like it was supposed to, with a high hashrate and with logical speed, possibly with some differences that can be called compromise :|
Still funnier: BIP148 breaks away, and now on the legacy chain, some decide to protect themselves from being overtaken with a hard fork, but one cannot find an agreement of that, so some split off with the Barry agreement (indeed activating segwit in doing so) ; others go to bigger blocks, some using BU, and some using Classic ; and finally some keep running bitcoin as it originally was.
The first page on most exchanges list the different flavours of bitcoin : it is such a mess that we ask Trump to decide in the end
