Me too, very optimistic, assuming we mean the same thing, thanks for posting.

But my first reaction to the title is “None, there is no future for Blockchain companies”.

Firstly I believe blockchain itself is history. It is genuinely scaleable distributed ledger beyond blockchain that is the future.

Secondly, “Company” implies a commercial entity, based on making a profit. I don’t believe there is any place for those in distributed ledger, only non-profits, because there does not seem to be anything that can be offered at profit, which cannot also be offered for free by a non-profit, therefore non-profits will always win in that space.
