Sorry, but we are very far from that.

For most people who know/use/own bitcoin, Bitcoin is just magical internet money. Most don't care about the internals.
And how many people know/use/own bitcoin? 3% of world population?

So first we need to grow that % substantially.
Then, from "magic internet money" we need a leap forward, where people understand that all that is enforced by math.
Then, maybe, with some luck, this system will be adopted in other aspects of our lives.
Will this mean "math governance"? I don't know, maybe. I am not even sure this will be adopted or will have a chance to be functional (Bitcoin/blockchain is not the universal solution for everything). But, even ignoring that part, we are very far from that.
