By the help segwit2x activation this time, everyone expected the bitcoin transaction fees will be reduced and block size increased with the faster confirmation time. But unfortunately nothing happened this time.
First of all, SegWit2X isn't activated, it's just SegWit. Second of all, confirmation times were never said to become faster. SegWit needs to be adopted in order to make a sizeable impact on the transaction fees.
Realistically, with SegWit Bitcoin should be able to fit much more transactions into one single block, and that without needing to actually increase the block size, which is a pretty solid characteristic.
It basically means that it will not result in the blockchain to unnecessarily grow larger when it isn't needed. But for that to happen we need services to set the first step, otherwise we'll see things progress extremely slow, which is bad.
