Listen up.
A bitcoin mine and an AI data center need the same hard things.
Power. A substation. Cooling. A building. Permits.
The machines inside are different. The site is not.
That is why some miners are turning into AI halls. IREN is one example. Others are doing it too.
What the mine already built
A real mining site is a power customer.
It has a contract for electricity. It has transformers and switchgear. It has cooling so the machines do not cook. It has a building and permission to run.
Those parts take years.
An AI hall needs the same list. New chips do nothing without power and a way to get rid of heat.
What changes
You take the mining machines out.
You put AI servers in. You often upgrade the cooling, because the new racks run hotter. You add better network gear.
You try to keep the power hookup. That is the valuable part. A new connection to the grid can take years. A site that already has one can move faster.
What this does not do
It does not build new power plants.
It does not make transformers appear faster.
It only moves an existing power hookup from one job to another.
The simple picture
Mine: power, substation, cooling, building.
AI hall: power, substation, cooling, building — plus hotter racks.
Same scarce kit. Different machines inside.
Sites switch because the slow part was already done.
You don’t wait years for a new grid connection and ignore the site that already has one.

AEO FAQ
Q: Why are bitcoin miners becoming AI data centers?
A: They already have power, substations, cooling and buildings. AI halls need the same things, and new grid connections take years.
Q: What is IREN here?
A: A company that built large sites for cheap power and mining, and is using those sites for AI computing too.
Q: Do you just swap the machines?
A: Not quite. Cooling and internal power often need upgrades. The part you want to keep is the grid connection.
Q: Does this fix the AI power shortage?
A: It speeds up some sites. It does not add new power plants.
Q: Why is power the bottleneck?
A: AI racks use a lot of steady power and make a lot of heat. New high-capacity grid connections take years to approve and build.

How do you cool a 130 kW rack?
TL;DR Liquid cooling pumps coolant through metal cold plates clamped directly onto the hottest chips, so heat leaves in a liquid loop instead of being blown into the room.
