I appreciate the technical work, but images like these challenge my confidence in Bitcoin.
The ownership is distributed, you can buy a seat on the board today, and share in the profits. (The shares are publicly trained)
Who cares whether "ownership" is distributed? What matters to the long term viability of Bitcoin is whether a government or some other bad actor could take over one or a few mining operations to gain control of the network.
It is extremely unlikely and expensive to maintain 51% of the network.
AM isn't even 5th in terms of total network hashrate, so we can probably relax, though it would be large for a private mine. The big ones on the list are large pools.
Really cool post thanks op!
