I think XT will be succesful in some way, even if the fork does not even happen: In pushing a blocksize increase.
I feel that many people are nowadays supporting a bigger block size due, in part to the XT move.
And I am not pro XT by any means. But that is my perception.
While I can understand this point of view it is plain wrong.
It was, is and will forever be nothing more than an attack on the network. A divisive attempt to break consensus and create a schism fork.
Productive collaboration between well intentioned actors in the ecosystem is considerably more effective in the resolution of a problem. This drama was a huge drain on those people. While Gavin & Mike gets to play politics and twiddle thumbs (or bake censorship code into Bitcoin), other developers can only sit there, withstand the barrage of reddit derps entitlement bullshit and persistent character assassination.
YET! Because these are very productive and brilliant people who have against all lazy hearsay been working insanely hard at actually scaling behind the scenes, we are apparently closing in on a very interesting chance for the actual leaders in the space to congregate and discuss what should actually happen with Bitcoin as we march away from the XT cesspool.
It was a defensive attack to prevent the network to be captured by the blockstream's guys.
They are very productive and brilliant for taking care of their own interest, no question about that.
