Stack Risk. We need to know how much CPU power entities have at their dosposal. If statistics aren't available, find data centers and energy breakdowns backout those costs and use sqftage to find amount of servers.

COmputing power growth rate is likely biggest metric tp assess how the tech industry is doing and possibly better at measuring an economy than GDP.

The risk asdociated with having elephant flow like ownership, e.g 20% controlling 80% could be catastrophic for numbers of reasons:

Lack of fault tolerance of core services

Lack of provacy due to vertical stack ownership

Ability to map users on internet

Ability to break cryptography

Extension of above, ability to control alt currency.

Ability to attack networks.

Etc. we need to get a pulse on this and it is a bigger existential threat than ai in short term.
