uhh. It exists. Its called Truthcoin and Augur.
And you think the Bitshares community isnt going to create their own competing versions of those?
Who's going to fund and develop it? The better question is if Bitshares does create their own, how much of this will include a lopsided experimential period where Dan and Dev teams figures out what works and doesn't work. Is it going to lead to another frantic and controversal merging? Bitshares lacks prediction market advisors and expertise. These guys are ahead in that category.
This answer assumes we will always operate in 1.0? In 2.0 there is nothing stopping even the boys from Augur coming to Bitshares with a worker proposal to integrate or introduce a version to BitShares. We vote, and in it goes. Why does it rely on Dan and team to be done?
Theory means nothing. ALthough it feels good to say it will happen in theory, things don't materialize within the execution phase. Execution is harder to achieve than theory.
I think Augur team will be focused on creating value on their own pipeline. They have a stake in improving Augur on Ethereum. Otherwise they will spread themselves thin.
This is a good look from the past: Remember when Microsoft became exclusive for IBM machines? Steve jobs felt betrayed by Bill Gates. But how did that work out for Microsoft? They turned into a operating software dynasty, while Apple floundered and nearly fell off the map,.
According to Peter Thiel, all startups should strive for exclusivity and monopolization.
