Would Bitcoin be dead for good?

Mike Hearn, a leading Bitcoin developer posted on Medium exposing some of the inner workings of the Bitcoin industry with a particular focus on deadlock between developers regarding how to increase the maximum number of transactions per second while also proposing a new version of bitcoin called BitcoinXT as a solution which will not activate till 75% of all clients working on Bitcoin are updated.
This is certainly not the first time Bitcoin has been declared dead since it's release but coming from one of it's lead developers the news certainly deserves some attention.
