For fucks sake not this again..
SegWit is a new transaction format this is more blockchain friendly. The few days of work required by wallets and so on to support it is really not a big deal considering the benefits of SegWit both short and long term. Even if we decided to hardfork to increase blocksize limit to 2mb or something miners can vote for SegWit still has to be implemented because of its other benefits. It is beyond me how someone who supposedly considers himself an expert in bitcoin is against SegWit.
