"Which is why a global, decentralized token, like bitcoin, still has a very bright future."
I agree. These permissioned blockchains will never be able to offer the utility, security and immutability that bitcoin can offer, but I'm sure they will find their niche somewhere.
I envision a future where these corporate blockchains will interact and compete with the decentralized chains.
Exactly. They say something like that in the IBM article actually.
