I view Segwit as that needed upgrade to the code that Bitcoin is badly needing. It should in turn speed up the transaction times, lower the fees back to a more low rate like it was originally and hopefully start fixing the huge backlog of transactions out there sitting unmoved and stalled. Bitcoin was never prepared for the huge factor of so many users so they really got to do something about these things if they ever want to become a mass adopted service, so Segwit is the key option they have. This version of it though, its a mess from what I heard, there is better codes proposed so its kind of why this back and forth undecided mess is going on because this one seems to benefit the big miner corporations while others seem to benefit the users, we have an impasse going one due to that sadly.
