Yup. It could be that the space really kicks off in terms of real usage in the private blockchain space first, at least in the short to medium term, until the technology evolves to the point where it can truely cater for public Dapps in a fully decentralised manner. Hybrids are definitely a huge part of it, especially for identity, health & insurance etc. But i would imagine a future where all of the blockchains, private, hybrid & public will be interconnected through permissioned bridges creating a sort of macro-hybrid blockchain of blockchains.
