Once the XBridge is completed and running, thats when all the fun + real hard work will take place IMO.

It will need constant tweaking, research, development, Clever managerial decisions, in order to mold the tech in an ever changing crypto landscape. Thats when I believe the true race amongst Blockchain Network providers will start.
Might we see competing tech merging? Are we going to be lucky enough we dont have a single provider (Like google) having 80% of the market share (at some point), but rather i.e. 10 players catering blockchain network with equal market share?
As history has shown us (with search engines), we are going down the same path, with all the obstacles, competitions and failures. Survival of the fittest.
